摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of removing deposits on an intermediate transfer body without causing downtime in which normal image forming operation cannot be performed.SOLUTION: When a normal image forming operation is started, a toner image of a first color is formed on a photoreceptor 1K. At the same time (or after the lapse of a short time), a toner image for a toner processing mode is formed on one of photoreceptors 1M, C, Y, which are located downstream. For example, the forming of the toner image for the toner processing mode is started on the photoreceptor 1Y and is completed before starting a normal image forming operation on the photoreceptor 1Y, and then a normal image forming operation is performed. For the toner image for the toner processing mode on an intermediate transfer belt 10, secondary transfer to a transfer paper sheet is not performed. Rather, it is conveyed to a belt cleaning device 19 as it is and is scraped and removed by a belt cleaning blade 19a.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus configured such that matter adhering to image carriers and a transfer body are efficiently removed by eliminating a time when regular image forming operation cannot be performed.
SOLUTION: The image forming apparatus includes photoreceptors on which images can be formed for each of colors, and a plurality of photoreceptors are arranged side by side along the moving direction of the transfer body to which images formed on the photoreceptors are transferred. The image forming apparatus recovers toner adhering to the surfaces of the photoreceptors or transfer body after the transfer by cleaning the toner. In transfer order of the images formed on the plurality of photoreceptors, before image formation which is to be executed on the photoreceptors at following stages, subsequent to image formation which is performed on the photoreceptor 1Y located most upstream in the moving direction of the transfer body, the image forming apparatus executes an adhering matter removal mode. In this mode, toner image formation different from the regular image formation is carried out in order to increase the amount of toner attached to the photoreceptors and transfer body. Then, the toner images formed in the adhering matter removal mode are cleaned off.
