Abstract

See full text

An image forming apparatus includes an image bearing member, a charging member, an exposure unit, a developing unit including a developer carrying member and a regulating member, a transfer member, a counting portion, a driving portion, and a controller. The controller carries out control so as to perform an image forming operation capable of forming a developer image, on the image bearing member, to be transferred onto a recording material and a non-image forming operation in which the developer image to be transferred onto the recording material is not formed on the image bearing member. Depending on each of count values in a plurality of regions acquired by the counting portion in a predetermined period, the controller controls the driving portion so as to change a rotation amount of the developer carrying member in a developing rotation operation for rotating the developer carrying member during the non-image forming operation.
