Abstract
An image forming apparatus includes a rotatable photosensitive member, a charging member, a developing device, a transfer member, a brush, a driving source and a control portion. The control portion controls the driving source to execute an image forming process, in which image formation on the recording material is executed, and a non-image-forming process, in which the photosensitive member is driven to rotate other than in the image forming process. The non-image-forming process between a first recording material and a second recording material, to which the image formation is executed following the first recording material, is defined as a first non-image-forming process, and the non-image-forming process between the second recording material and a third recording material is defined as a second non-image-forming process. The control portion determines a time of the second non-image-forming process based on history information correlating with a usage amount of the photosensitive member and a time of the first non-image-forming process.
