Abstract
A developer collection container includes a developer storing portion having first and second end portions in a longitudinal direction thereof. A developer supply opening is provided on the first end portion through which the developer is supplied into the developer storing portion. A rotation member is rotatably provided so as to extend substantially from the first end portion to the second end portion. The rotation member rotates so as to convey the developer in the longitudinal direction of the developer storing portion. In a first region closer to the first end portion, the rotation member conveys the developer in a direction from the first end portion toward the second end portion with a conveying power which is larger than a conveying power with which the rotation member conveys the developer in a second region closer to the second end portion.

11. A developer collection container comprising:
-
a developer storing portion for storing a developer, said developer storing portion having an elongated shape and having first and second end portions in a longitudinal direction thereof; a developer supply opening provided on said first end portion of said developer storing portion through which the developer is supplied into said developer storing portion, and a rotation member rotatably provided in said developer storing portion so as to extend substantially from said first end portion to said second end portion in said longitudinal direction of said developer storing portion, said rotation member rotating in a predetermined direction so as to convey the developer in said longitudinal direction of said developer storing portion, wherein, in a first region closer to said first end portion, said rotation member conveys the developer in a direction from said first end portion toward said second end portion with a conveying power which is larger than a conveying power with which said rotation member conveys the developer in a second region closer to said second end portion, wherein said rotation member conveys the developer in said second region in a direction opposite to a direction in which said rotation member conveys the developer in said first region. - View Dependent Claims (12, 13)

14. A developer collection container comprising:
-
a developer storing portion for storing a developer, said developer storing portion having an elongated shape and having first and second end portions in a longitudinal direction thereof; a developer supply opening provided on said first end portion of said developer storing portion through which said developer is supplied into said developer storing portion, and a rotation member rotatably provided in said developer storing portion so as to extend substantially from said first end portion to said second end portion in said longitudinal direction of said developer storing portion, said rotation member rotating in a predetermined direction so as to convey said developer in said longitudinal direction developer storing portion, wherein, in a first region closer to said first end portion, said rotation member conveys said developer in a direction from said first end portion toward said second end portion with a conveying power which is larger than a conveying power with which said rotation member conveys said developer in a second region closer to said second end portion, wherein said rotation member conveys said developer in said second region in a direction opposite to a direction in which said rotation member conveys said developer in said first region, and wherein said rotation member conveys said developer in said first region with a constant conveying power, and conveys said developer in said second region with a conveying power that decreases in a direction from said second end portion toward said first end portion of said developer storing portion.
