Abstract
An image forming apparatus includes a driving unit having a first drum gear, a first coupling member, a second drum gear, and a second coupling member. The first coupling member is provided at a first position of the first drum gear. The second coupling member is provided at a second position of the second drum gear and is configured to rotate together with the second drum gear. A first angle from a first meshing position to a first transfer position in a first direction and a second angle from a second meshing position to a second transfer position in a second direction are different from each other. The second position of the second drum gear is shifted from a position corresponding to the first position of the first drum gear by a difference between the first angle and the second angle in a direction opposite of the second direction.
