Abstract:
An image forming apparatus, having a casing, a cover, a first motor, a photosensitive drum, a second motor, a developing motor, a clutch, a contact/separation cam, a switching cam, and a controller, is provided. The controller conducts a first process, in which, when the cover is moved from an open position to a closed position, the controller drives the first motor to rotate the photosensitive drum without causing rotation of the developing roller; and a second process, in which, after a lapse of a first period since the controller started driving the first motor, the controller drives the second motor to move the contact/separation cam from the first phase to the second phase and move the switching cam from the first phase to the second phase causing the developing roller to be moved from the contacting position to the separated position while the photosensitive drum is rotating.
