Abstract
An image forming apparatus includes a mechanism configured to bring an intermediate transfer member into a first state contacting first and second drums and a second state separating from the first drum and contacting the second drum. The image forming apparatus is operable in a first mode of using the first and second drums in the first state, a second mode of using only the second drum in the second state, and a third mode of using only the second drum in the first state. If an image forming retry involving cleaning a transfer portion due to a recording medium conveyance delay in the third mode is to be performed, a controller changes over the third mode to the second mode without stopping rotation of the second drum to perform image formation on a recording medium fed by restart of a feeding operation.
