An image forming apparatus includes: a drum unit including a photosensitive drum; a belt unit; and a secondary transfer member. The belt unit includes: a first roller; a second roller spaced apart from the first roller; an intermediate transfer belt supported by the first roller and the second roller; and a primary transfer member. The intermediate transfer belt includes: a first portion; and a second portion. The first portion has an upstream end and a downstream end in a first direction. The second portion has an upstream end and a downstream end in a second direction. The primary transfer member is configured to transfer a toner image from the photosensitive drum to the first portion. The secondary transfer member is capable of contacting the downstream end of the second portion, and is configured to transfer the toner image from the intermediate transfer belt to a sheet.

An image forming apparatus includes: a first image forming unit that forms an image by using first toner; a second image forming unit that forms an image by using another kind of toner different from the first toner; a transfer unit that transfers the images formed by the first image forming unit and the second image forming unit onto an intermediate transfer body and then onto a recording medium; and a setting unit that sets an order of the images that are transferred onto the intermediate transfer body so that the image formed from the other kind of toner is transferred onto an independent image formed from the first toner transferred onto the intermediate transfer body in a case where the independent image formed from the first toner is to be formed on the recording medium.

A photo drum may be to receive a color separation. A controller may be to change a location of the color separation on the photo drum from a first location to a second location when a separation location history for the color separation is outside of a threshold range.

A transfer device includes a pressed unit, a rotatable roller, and a pressing member. The pressed unit is movably supported and includes a first non-rotatable shaft portion and a second non-rotatable shaft portion. The rotatable roller is rotatably supported by the first non-rotatable shaft portion of the pressed unit. The pressing member contacts the second non-rotatable shaft portion of the pressed unit and presses the pressed unit. The second non-rotatable shaft portion has an axial center aligned with an axial center of the first non-rotatable shaft portion.

An image forming apparatus includes: a drum unit including a photosensitive drum; a belt unit; and a secondary transfer member. The belt unit includes: a first roller; a second roller spaced apart from the first roller; an intermediate transfer belt supported by the first roller and the second roller; and a primary transfer member. The intermediate transfer belt includes: a first portion; and a second portion. The first portion has an upstream end and a downstream end in a first direction. The second portion has an upstream end and a downstream end in a second direction. The primary transfer member is configured to transfer a toner image from the photosensitive drum to the first portion. The secondary transfer member is capable of contacting the downstream end of the second portion, and is configured to transfer the toner image from the intermediate transfer belt to a sheet.

An intermediate transfer medium onto which a toner image is transferred is provided. The intermediate transfer medium comprises a base layer and an elastic layer overlying the base layer. The elastic layer contains spherical fine particles to form an irregular surface, and the spherical fine particles have a volume resistivity of 110.sup.4 .Math.cm or more and less than 110.sup.0 .Math.cm.

A method for manufacturing an intermediate transfer belt having at least a base layer and a surface layer formed in contact with a surface of the base layer, includes: irradiating a surface of the base layer with a laser such that Rz (in accordance with JIS-B0601-2001) is 0.2 m or more and equal to or less than a half of a film thickness of a surface layer to be formed; and forming a surface layer on the surface of the base layer irradiated with the laser.

A pressing device includes an intermediate transfer unit, a secondary transfer unit, a presser, and a drive transmitter. The intermediate transfer unit transfers and conveys a toner image. The secondary transfer unit faces the intermediate transfer unit to form a nip portion between the secondary transfer unit and the intermediate transfer unit and transfers the toner image onto a conveyed material at the nip portion. The presser applies a pressing force for pressing the secondary transfer unit to the intermediate transfer unit at the nip portion. The drive transmitter transmits the pressing force and a conveyance driving force to a driven transmitter of the secondary transfer unit, is restricted in position by the presser, and is movable together with the presser.

An intermediate transfer belt assembly includes an intermediate transfer roller located on an inner side of an intermediate transfer belt to support the intermediate transfer belt, an accommodation portion to accommodate foreign matter, the accommodation portion having an inlet open toward the intermediate transfer belt, and a shutter to open or close the inlet.

An image forming apparatus includes an image carrying member, an intermediate transfer belt, a primary transfer roller, a first belt support roller, a secondary transfer roller, a second belt support roller, a current output portion, a current sensing portion, and a control portion. The current output portion passes across the secondary transfer roller a secondary transfer current as part of an output current. The current output portion and the second belt support roller are electrically connected together. The current sensing portion senses a leakage current passing from the first belt support roller via the intermediate transfer belt to the second belt support roller. The control portion sets the output current such that the secondary transfer current has a value given by subtracting a leakage current from the output current and keeps the voltage on the second belt support roller between ?50 V and 50 V, inclusive.
