Abstract
An image forming apparatus includes a photosensitive drum, a developing member, an applying device forming a developing potential on the developing member, a driver rotationally driving the developing member, and a controller. The controller selectively executes an operation in first and second modes by controlling a circumferential speed ratio of a circumferential speed of the developing member to a circumferential speed of the drum and a potential difference between a surface potential of the image bearing member in a region where an electrostatic latent image is formed and the developing potential. In the first mode, the ratio is a first ratio of 50% to 100% and the potential difference is a first potential difference, and in the second mode the ratio is a second ratio larger than the first ratio and less than 150% and the potential difference is a second potential difference less than the first potential difference.
