An image forming apparatus includes a photoreceptor drum, a developing roller, and a control section. The photoreceptor drum is configured to form an electrostatic latent image on a surface thereof in accordance with image data. The developing roller has a surface for bearing a two-component developer at least a partial region of which faces the photoreceptor drum and is configured to be driven so as to feed the developer to the photoreceptor drum. The control section is configured to detect a print coverage for image data to be used during continuous formation of images in accordance with plural image data items and then set a relative velocity of the developing roller to the photoreceptor drum to a higher value when the print coverage is relatively high and set the relative velocity to a lower value when the print coverage is relatively low.
