Abstract
A photosensitive drum extends in an axial direction. An irradiating unit includes a first reacting portion and a second reacting portion spaced from each other in the axial direction. A moving member includes a first acting portion and a second acting portion spaced from each other in the axial direction. The first acting portion and the second acting portion of the moving member act on the first reacting portion and the second reacting portion respectively, in response to attachment of the developing unit to a main body, such that the irradiating unit moves from the retracted position to the proximate position with respect to the photosensitive drum, and cancel the actions on the first reacting portion and the second reacting portion respectively, in response to removal of the developing unit from the main body, such that the irradiating unit moves from the proximate position to the retracted position.
