Abstract
An image forming apparatus to perform an image forming operation for forming an image on a transfer material includes a photosensitive drum, a moving member, a detection unit, and a control unit. The detection unit detect information about a first movement in which the moving member moves from an open position to a shielding position or a second movement in which the moving member moves from the shielding position to the open position. During execution of a non-image forming operation, the control unit executes a multiple switching operation for performing a switching operation a plurality of times. The switching operation is an operation in which the control unit stops the photosensitive drum from being driven and then rotatably re-drives the photosensitive drum. Where the detection unit detects the information about the first movement or the second movement, the control unit performs control to execute the multiple switching operation.
