Image forming apparatus featuring first and second cleaners operable on the basis of an interval of an image forming process during a continuous image forming process

摘要

An image forming apparatus includes an image bearing member on which an electrostatic image is formed; a development device which develops the electrostatic image formed on the image bearing member, and forms a toner image; a first transfer device which transfers the toner image on the image bearing member to an intermediate transfer member at a first transfer position; a first cleaning device for cleaning the image bearing member; a second transfer device which transfers the toner image on the intermediate transfer member to a recording material at a second transfer position; a second cleaning device for cleaning the intermediate transfer member; and a determining device which determines, whether the toner on the intermediate transfer member is to be cleaned by the second cleaning device or by the first cleaning device through the image bearing member, based an interval of an image forming process during a continuous image forming process.
