摘要： An image forming apparatus includes a plurality of image carriers, an intermediate transfer belt, a plurality of transfer rollers, a print control portion, and a contact pressure control portion. The plurality of transfer rollers are provided in such a way as to be in contact with the intermediate transfer belt at positions respectively corresponding to the image carriers. The print control portion executes a print process in a first print mode or a second print mode that are set in advance. The contact pressure control portion, when the print process is executed in the first print mode, reduces a contact pressure of one or more transfer rollers that are, among the plurality of transfer rollers, disposed on a downstream side in a conveyance direction of the intermediate transfer belt, to be lower than a contact pressure in the second print mode.

摘要： An intermediate transfer unit includes an endless intermediate transfer belt to which a toner image is primarily transferred from an image carrying member, a driving roller that conveys the intermediate transfer belt with the primarily transferred toner image to a secondary transfer position for a sheet material, and a cleaning device which cleans a peripheral surface of the driving roller around which the intermediate transfer belt is wound.

摘要： A developing device includes a storing portion, a stirring member, a developing roller, a shield plate, and a guide portion. The storing portion stores developer. The stirring member is rotatably provided in the storing portion and stirs the developer in the storing portion by being rotationally driven in a predetermined first rotation direction. The developing roller is rotatably provided above the stirring member, has a magnet that attracts the developer in the storing portion by a magnetic force, and is rotationally driven in a predetermined second rotation direction. The shield plate is made of a nonmagnetic material and provided at a facing position where the developing roller and the stirring member face each other. The guide portion is provided more on an upstream side in the first rotation direction than the facing position, and guides the developer from the storing portion to the developing roller side.
