Image forming apparatus having photosensitive members and blades in contact with respective photosensitive members

摘要

An image forming apparatus includes a fixing member, first and second image forming portions, and a processor. In the first and second image forming portions, first and second blades are respectively in contact with first and second photosensitive members. A distance between the first image forming portion and the fixing member is shorter than a distance between the second image forming portion and the fixing member. The processor controls a first image forming portion to perform a toner supply operation in which a first supply member supplies toner amounting to a first quantity per a prescribed rotation amount of the first photosensitive member, and controls the second image forming portion to perform a toner supply operation in which the second supply member supplies toner amounting to a second quantity per the prescribed rotation amount of the second photosensitive member. The second quantity is smaller than the first quantity.

1. An image forming apparatus comprising:
a first image forming portion comprising;
a first photosensitive member configured to rotate;a first supply member configured to supply toner of first color to the first photosensitive member; anda first blade in contact with the first photosensitive member; a second image forming portion comprising:
a second photosensitive member configured to rotate;a second supply member configured to supply toner of second color to the second photosensitive member; anda second blade in contact with the second photosensitive member,a fixing member configured to thermally fix toner on a sheet, wherein the fixing member, the first image forming portion, and the second image forming portion are arranged in such a positional relation that a distance between the first image forming portion and the fixing member is shorter than a distance between the second image forming portion and the fixing member; and a processor configured to perform:
controlling, while an image forming operation by the first image forming portion is not performed, the first image forming portion to perform a toner supply operation in which the first supply member supplies, to the first photosensitive member, toner amounting to a first quantity per a prescribed rotation amount of the first photosensitive member; andcontrolling, while an image forming operation by the second image forming portion is not performed, the second image forming portion to perform a toner supply operation in which the second supply member supplies, to the second photosensitive member, toner amounting to a second quantity per the prescribed rotation amount of the second photosensitive member, the second quantity being smaller than the first quantity.
