Abstract
In an image forming apparatus, an image bearing member and a cleaning member are in contact with each other to form a collection nip. A conveyance member is in contact with the image bearing member to form a conveyance nip. The controller executes a maintenance mode including a toner supply process, an output process, and a sheet feeding process. The toner supply process supplies at least part of the image bearing member with a predetermined amount of toner. The output process controls a circuit to output the cleaning voltage to the cleaning member. The sheet feeding process controls the feeding member to start feeding the sheet so that the sheet passes the conveyance nip in coincidence with the at least part of the image bearing member passing the conveyance nip after the at least part of the image bearing member has once passed the collection nip.
