Abstract: A cleaning apparatus is provided with a cleaning roller that is positioned so as to be in contact with a photosensitive drum, and with a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of this cleaning roller. The toner layer thickness regulating member is formed by a toner layer thickness regulating roller that rotates in contact with the cleaning roller.

Abstract: In an image forming apparatus, a control section 41 adjusts the surface potential of a photoconductor or the developing potential of a developer carrying member based on the detection result of a surface potential sensor 44, and performs first correction whereby, relative to the reference value of the applied bias of a charger 2 or the developing bias of the developer carrying member in a developing unit 4 as observed during potential adjustment, the applied bias or the developing bias is varied so as to keep constant the potential difference between the surface potential of the photoconductor and the developing potential of the developer carrying member during image formation. The control section also performs second correction whereby the applied bias or the developing bias is restored to the reference value over a predetermined period after the completion of continuous image formation.
