Abstract: An image forming device includes: a photoreceptor that forms a toner image; a brush that abuts the photoreceptor to clean a surface of the photoreceptor; an operator that changes a toner residual amount in the brush; and a hardware processor that performs in-brush toner amount control to allow the operator to operate such that the residual amount approaches a set value when a toner image for printing according to a print job is not formed on the photoreceptor as the toner image.

Abstract: A fixing device is for fixing a toner image on a recording medium an image forming apparatus. The fixing device includes a fixing belt, a heating member, a nip area member, a pressing member, and a protrusion. The fixing belt is held by the heating member and the nip area member. The pressing member presses the fixing belt against the nip area member while being rotationally driven. The toner image is fixed on the recording medium in a nip area where the pressing member presses the fixing belt against the nip area member. The protrusion is in contact with the inner surface of the fixing belt. In the fixing device, the fixing belt is in contact with small areas only other than the heating area and the nip area to reduce the heat loss.
