Abstract
An image forming device includes an intermediate transfer member to which a toner image formed on an image bearing member is primarily transferred and which is able to simultaneously support a plurality of toner images, a secondary transfer member for secondarily transferring a toner image held on the intermediate transfer member to a sheet, a cleaning unit for removing the toner images from the intermediate transfer member after the secondary transfer, and a feeding member for feeding a sheet into the secondary transfer member. The secondary transfer member features a sheet-delay transfer mode in which a subsequent toner image on the intermediate transfer member is transferred if a previous toner image on the intermediate transfer member is out of sync with the timing at which the toner image is transferred to the fed sheet.
