Abstract
A image forming apparatus includes a rotatable image bearing body, an exposing unit that irradiates the image bearing body to form a latent image, a developer bearing body that develops the latent image to form a developer image, a transfer unit that transfers the developer image to a recording medium, a feeding unit that feeds the recording medium, a density detecting unit that detects a developer density of the developer image transferred to the recording medium, and a speed difference control unit that controls a difference of a circumferential speed of the image bearing body and a feeding speed of the recording medium fed by the feeding unit. The speed difference is controlled based on a density of a thin line pattern transferred to the recording medium detected by the density detecting unit.
