Image forming apparatus

An image forming apparatus capable of performing an image forming operation for forming an image on a transfer material, the image forming apparatus comprising:

• a photosensitive drum that is rotatable;
• a charging member configured to come into contact with the photosensitive drum to form a charging portion and charge a surface of the photosensitive drum at the charging portion;
• a developing member configured to supply a toner to the surface of the photosensitive drum charged by the charging member;
• a transfer member configured to come into contact with the photosensitive drum to form a transfer portion and transfer the toner formed on the photosensitive drum to the transfer material at the transfer portion;
• a moving member configured to move between an open position where an inside of the image forming apparatus is exposed and a shielding position where the inside of the image forming apparatus is shielded;
• a detection unit configured to detect information about a first movement in which the moving member moves from the open position to the shielding position or a second movement in which the moving member moves from the shielding position to the open position;
• a drive source configured to rotatably drive the photosensitive drum;
• and
• a control unit configured to control the drive source,
• wherein, during execution of a non-image forming operation different from the image forming operation, the control unit performs control to execute a multiple switching operation for performing a switching operation a plurality of times,
• wherein the switching operation is an operation in which the control unit stops the photosensitive drum in a state of being driven and then rotatably re-drives the photosensitive drum, and
• wherein, in a case 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.
