Color image forming apparatus and method of controlling same
First Claim
1. A method of controlling an image forming apparatus for forming an image on a transfer medium, comprising:
- a determination step of determining that a characteristic of the transfer medium has changed;
an entering step for allowing an operator to enter whether or not a density sensing sequence is to be executed, based upon the determination of the change in the characteristic of the transfer medium;
a step of executing the density sensing sequence in a case where the fact that said sequence is to be executed has been entered, the density sensing sequence including a sensing step of forming an image, which is for sensing density, on the transfer medium, and sensing this density-sensing image on the transfer medium; and
a step of deciding image forming conditions of the image forming apparatus based upon result of sensing density in the density sensing sequence.

Abstract
An image of stabilized tint is output even if a supplied transfer medium is changed to a transfer medium of a different surface gloss or type of paper. If the supplied transfer medium has changed, the tint of a corrective image formed on the transfer medium is sensed, a tint correction of an image forming portion is performed based upon result of sensing, and corrective data of the tint correction and information relating to the transfer medium is stored. If a change of the transfer medium is sensed subsequently, a determination is made as to whether the transfer medium is substantially the same transfer medium, based upon the stored information relating to the transfer medium. If the transfer medium is substantially the same, then image processing is executed based upon the stored corrective data.

9. An image forming apparatus comprising:
-
an image forming unit adapted to form an image on a transfer medium; a sensor adapted to sense an image, which is for sensing density, formed by said image forming unit; a control unit adapted to decide image forming conditions of said image forming unit based upon result of sensing by said sensor; a determination unit adapted to determine that a characteristic of the transfer medium has changed; and input means for allowing an operator to enter whether or not a density sensing sequence is to be executed, based upon the determination of the change in the characteristic of the transfer medium; said apparatus executing the density sensing sequence in a case where the fact that the sequence is to be executed has been entered, the density sensing sequence including a forming the image, which is for sensing density, on the transfer medium, and sensing this density-sensing image on the transfer medium using said sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15)
