2. An apparatus according to claim 1, wherein the first-procedure signal is a signal indicating that there is another page of image data to be transmitted from the other apparatus upon completion of transmission therefrom of one page of image data.

3. An apparatus according to claim 1 or 2, wherein the recovery operation is not executed when the second procedure signal, which is a signal indicating that there is no additional image data to be transmitted from the other apparatus upon completion of transmission therefrom of one page of image data, is received.

4. An apparatus according to claim 3, further comprising preservation means for performing preservation processing of said recording means, wherein said preservation means performs preservation processing when the second procedure signal is received and is a signal indicating that there is no additional image data to be transmitted from the other apparatus upon completion of transmission therefrom of one page of image data.

5. An apparatus according to claim 1 or 2, wherein said communication means transmits to the other image communication apparatus a signal indicating completion of an image data reception standby operation after the predetermined recovery operation is completed.

6. An apparatus according to claim 1, wherein said recovery means supplies ink to said recording means to eject ink forcibly therefrom.

7. An apparatus according to claim 1, wherein the recovery operation includes an idle ejection operation by said recording means.

8. An apparatus according to claim 1 or 2, wherein said recording means has nozzles of one line corresponding to a width of the largest recording member which can be used in recording.

9. An apparatus according to claim 1 or 2, wherein said recording means comprises a plurality of nozzles and a plurality of energy generating elements driven according to the image data thereby ejecting ink.

10. An apparatus according to claim 9, wherein said recording means has nozzles of one line corresponding to a width of the largest recording member which can be used in recording.

11. An apparatus according to claim 9, wherein the energy generating elements comprise electro-thermal conversion elements for generating bubbles thereby ejecting ink.

12. An image communication apparatus adapted to communicate with another image communication apparatus, comprising:

communication means for receiving, from the other image communication apparatus, image data and a procedure signal associated with the communication of image data from the other image communication apparatus;

recording means for ejecting a droplet of ink onto a recording member in accordance with image data received by said communication means;

recovery means for performing a predetermined recovery operation of said recording means;

preservation means for performing a preservation operation for said recording means;

discriminating means for discriminating a procedure signal received by said communication means after the end of reception of one page of image data;

recovery control means for causing said recovery means to perform the predetermined recovery operation in accordance with a discrimination result by said discrimination means when the procedure signal indicates that additional image data to be transmitted from the other image communication apparatus is existent; and

preservation control means for causing said preservation means to perform the preservation operation for said recovery means in accordance with a discrimination result by said discrimination means when the procedure signal indicates that additional image data to be transmitted from the other image communication apparatus is not existent.

13. An apparatus according to claim 12, wherein said recording means has nozzles of one line corresponding to a width of a largest recording member which can be used in recording.

14. An apparatus according to claim 12, wherein said recording means comprises a plurality of nozzles and a plurality of energy generating elements driven according to received image data.

15. An apparatus according to claim 14, wherein said recording means has nozzles of one line corresponding to a width of a largest recording member which can be used in recording.

16. An apparatus according to claim 14, wherein said energy generating elements comprise electro-thermal conversion elements for generating bubbles thereby ejecting ink.

17. An apparatus according to claim 12, wherein said communication means transmits to the other image communication apparatus a signal indicating completion of an image data reception standby operation after the predetermined recovery operation is completed.

18. An apparatus according to claim 17, wherein said recovery means supplies ink to said recording means to eject ink forcibly therefrom.

19. An apparatus according to claim 17, wherein the predetermined recovery operation includes an idle ejection operation by said recording means.

20. An apparatus according to claim 17, wherein said recording means has nozzles of one line corresponding to a width of the largest recording member which can be used in recording.

23. An apparatus according to claim 21, wherein the energy generating elements comprise electro-thermal conversion elements for generating bubbles thereby ejecting ink.

24. An image communication apparatus for recording an image on a recording material according to received data using a recording head having a plurality of recording elements for ejecting ink, the apparatus comprising:

communication means for communicating a procedure signal related to a communication between communication parties and for communicating image data;
