Abstract
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.
