PROBLEM TO BE SOLVED: To prevent a toner excessive area from being formed between a developing roller and a layer thickness regulating roller. SOLUTION: The image forming apparatus includes: a developing roller 12-2 for supplying developer held on its periphery to a photoreceptor drum 10, while rotating in a first direction, and developing an electrostatic latent image formed on the photoreceptor drum 10; a layer thickness regulating roller 44 for regulating the layer thickness of developer held on the developing roller 12-2; a developing-roller drive motor 101a for rotating and driving the developing roller 12-2; and a control section 100 for controlling the developing-roller drive motor 101a such that when an electrostatic latent image on the photoreceptor drum 10 is not developed, the developing roller 12-2 is rotated in a second direction R2 opposite to the first direction R1.
