Abstract
An image forming apparatus includes a photosensitive member, a charging member, an exposure member, a rotatable developer carrying member, a voltage source, and a controller configured to control the voltage source so that when a thickness of the surface layer of the photosensitive member is a first thickness, a developing bias voltage including an oscillating portion having an oscillating voltage and a rest portion having a substantially constant voltage alternately repeated is outputted. When the thickness of the surface layer of the photosensitive member is a second thickness smaller than the first thickness, a developing bias voltage in which the rest portion is not included or is shorter than the rest portion when the thickness of the surface layer is the first thickness is outputted.
