Abstract
An image forming apparatus includes a developing portion, a driving-side shaft coupling, a movement supporting mechanism, a movement member, a separating member, and a displacement member. The developing portion includes a developing roller that develops an electrostatic latent image formed on an image-carrying member, and a driven-side shaft coupling that is provided on the developing roller. The driving-side shaft coupling transmits driving force, via the driven-side shaft coupling, to the developing roller. The movement supporting mechanism movably supports the developing roller between a developing position and a separated position. The displacement member applies a force to the movement supporting mechanism, and positions the developing roller at the developing position. When the movement member moves further after the driven-side shaft coupling has separated from the driving-side shaft coupling, the displacement member moves the developing roller from the developing position to the separated position.
