Abstract
An image forming apparatus includes a first rotating unit, an image carrier, an electrostatic latent image forming unit, a third rotating unit, an intermediate transfer body, first and second transfer units, and the following elements. A developing device includes a rotating body, a second rotating unit, plural developing units. A supply unit supplies a bias to a developer carrying member of each developing unit. A setting unit sets the bias to a first condition to develop the latent image of a first color at least while the latent image is being located at the developing position, and sets the bias to a second condition to suppress transferring of the toner in the subsequent developing unit to the image carrier after the second rotating unit starts rotating the rotating body from a waiting position and before stopping rotating the rotating body and locates the subsequent developing unit at the developing position.
