Abstract
An image forming apparatus includes an image bearing member on which an electrostatic latent image is formed; an image bearing member charging unit which applies an image bearing member charging voltage; a developer bearing member to which developing voltage for developing the electrostatic latent image on the image bearing member is applied and which bears and transports a developer; a primary transfer unit which transfers a developer image on the image bearing member to an intermediate transfer member; and a charging member which charges the developer on the intermediate transfer member. The developer image is first primarily transferred and then secondarily transferred to a recording material. The image forming apparatus operates in a first mode in which a residual developer on the intermediate transfer member after the secondary transfer is electrostatically removed from the intermediate transfer member, and a second mode.
