A drum cleaner cleans a circumferential surface of a photosensitive drum. A toner pipe allows passage of toner that is recovered from the drum cleaner to a toner container. The toner pipe has a discharge port configured to discharge toner in the toner pipe. The toner container includes a toner discharge port, a toner reception port, and a toner conveyor. The toner discharge port discharges toner in the toner container. The toner reception port receives toner discharged from the discharge port of the toner pipe. The toner conveyor conveys toner from the toner reception port toward the toner discharge port. A development housing includes a development reception port and a development discharge port. The development reception port receives toner discharged from the toner discharge port. The development discharge port discharges, to the toner pipe, toner that is retuned from the development housing to the toner container.

An image forming apparatus includes an image bearing member, a brush, and a controller. The controller controls so that, in a case where, in a state where a recording material trailing edge in a conveyance direction is sandwiched at a transfer portion, an area of the image bearing member in the conveyance direction where the recording material is sandwiched in a direction perpendicular to the conveyance direction is a first area, and an area of the image bearing member in the conveyance direction where the recording material is not sandwiched is a second area, a first potential difference formed between a surface potential formed on the second area and a brush voltage, which is based on first information, when the second area reaches the brush and a second potential difference formed between the second area surface potential and the brush voltage, which is based on second information, are different.
