Abstract
In an image forming apparatus having a developing rotary, when a positive direction refers to a circumferential direction of the developing rotary in which the portion of the developing rotary facing a photosensitive drum moves in the same direction as the movement of the circumference of the photosensitive drum, a clear developing unit is farther from the developing unit positioned in the negative direction relative to the clear developing unit than from the developing unit positioned in the positive direction relative to the clear developing unit.
