Claim:
1. An image forming apparatus, comprising: a rotator rotatably supported and configured to receive toner at a predetermined reception position, carry and convey the toner to a contact position at which the rotator contacts an image carrying member on which an electrostatic latent image is formed based on image data, and supply the toner to the image carrying member at the contact position; a driving control portion configured to control rotation of the rotator so as to rotate the rotator during a developing period in which the electrostatic latent image is developed, and stop the rotation of the rotator after a predetermined set time has elapsed since an end of the developing period; and a layer thickness control portion configured to cause the rotator to carry the toner by controlling a potential difference between a potential of the rotator and a predetermined potential so that the toner on the rotator at the contact position has a first layer thickness during the developing period and has a second layer thickness while the rotation of the rotator is stopped, the second layer thickness being thicker than the first layer thickness.
