摘要： An image forming apparatus of the present disclosure includes a plurality of image forming portions, an intermediate transfer unit, a secondary transfer member, a belt cleaning device, and a control portion. The intermediate transfer unit includes an intermediate transfer belt, a plurality of primary transfer members, a drive roller, a tension roller, and a contacting/separating mechanism. The belt cleaning device includes a cleaning member which faces the tension roller with the intermediate transfer belt therebetween. In a withdrawal mode, the cleaning member is moved by pressing force of the tension roller further into a housing from an opening portion as compared with in a printing mode. The control portion is capable of executing, while image formation is not being performed, a transfer toner collection mode in which the intermediate transfer belt and the belt cleaning device are driven in the withdrawal mode.

摘要： An image forming apparatus includes an image carrier, a rotating brush, a collecting roller, a cleaning blade, a sealing member and a side sealing member. The sealing member has an extension part extending outside from each end of the collecting roller in an axial direction. The sealing member comes into contact with the collecting roller between a contact area between the rotating brush and the collecting roller and the cleaning blade and then prevents backflow of the residue. The side sealing member lifts the extension part toward the collecting roller on an outside at a predetermined interval from a position corresponding to each side edge of a maximum-width sheet passing region on the image carrier.

摘要： An image forming apparatus includes a transfer processing portion, a detection processing portion, a correction processing portion, and an adjustment processing portion. The transfer processing portion transfers a detection toner image to outside an output area of a transfer object to which a toner image as an output target is transferred from an image-carrying member. The detection processing portion detects a density of the detection toner image that has been transferred to the transfer object by the transfer processing portion. The correction processing portion corrects a detection result of the detection processing portion based on an amount of toner transferred from the image-carrying member to the output area at a transfer timing when the detection toner image is transferred. The adjustment processing portion adjusts an image forming condition based on the detection result after correction by the correction processing portion.

摘要： An image forming apparatus includes a developing current detecting portion, a control portion, and a deviation detecting portion. The developing current detecting portion detects a developing current that flows between a developing device and a photoconductor drum during development of an electrostatic latent image. The control portion causes the exposure device to form electrostatic latent images of at least two patch images at different positions from each other and at different timings from each other in a main scanning direction. The deviation detecting portion detects deviation of one of the exposure device and the photoconductor drum with respect to the other based on a detection timing at which the developing current is detected during development of the electrostatic latent images of the at least two patch images.
