摘要： An image forming apparatus includes a transfer unit that transfers a toner image to a recording medium; a non-white toner image forming unit that forms a non-white toner image on the transfer unit by using non-white toner having a non-white color that differs from white; a white toner image forming unit that forms a white toner image on the transfer unit by using white toner that is white in color after the non-white toner image is formed on the transfer unit; and a control unit that controls an amount of the white toner used by the white toner image forming unit to form the white toner image so that the amount of the white toner is smaller when the non-white toner image is formed under the white toner image than when no toner image is formed under the white toner image.

摘要： An image forming apparatus includes an image carrier that holds an image, a developer carrier that holds a developer to be supplied to the image carrier, a transport member that transports the developer in an axial direction of the developer carrier, and a restraint member that restrains the developer, which has scattered as a result of being transported by the transport member, from moving toward the developer carrier.

摘要： A transport mechanism includes: a container that stores a specific developer; a transport body that transports the developer in an axial direction of a shaft about which the transport body rotates in the container while stirring the developer; a bearing that supports the transport body such that the transport body is rotatable about the shaft; and a restricting portion that has a substantially annular shape and a maximum magnetic force of about 20 mT or greater and about 50 mT or smaller and restricts the transportation of the developer past the restricting portion by surrounding the shaft, the restricting portion being provided nearer to a side on which the transport body transports the developer than the bearing in the axial direction of the shaft.

摘要： A developing device includes a developing sleeve and a regulation portion. The developing sleeve includes a magnetism generating portion to which magnetic poles are attached. The developing sleeve holds a developer on an outer circumferential surface. The regulation portion includes a magnetic plate. A first segment connecting a peak position of the magnetic pole disposed at a position facing the magnetic plate and an axial center of the developing sleeve has an angle, with respect to a second segment connecting the magnetic plate and the axial center, equal to or less than 7 degrees on a downstream side in a rotation direction of the developing sleeve and equal to or less than 6 degrees on an upstream side in the rotation direction. An angle of a half value width of the magnetic pole is equal to or greater than 41 degrees to equal to or less than 52 degrees.

摘要： An image forming apparatus includes an image forming section and a controller. The image forming section transfers a toner image to a transfer target and includes plural developing units. The plural developing units include a first developing unit and at least one second developing unit. The plural developing units each include an image holding body and a developing roller. The image holding body has an outer circumferential surface and is rotated. The controller controls the image forming section so that, when a low-area-coverage portion and a high-area-coverage portion are disposed adjacent to each other and are formed by the first developing unit, a correction toner image is superposed on a boundary portion, where the low-area-coverage portion and the high-area-coverage portion are adjacent to each other, by the at least one second developing unit.
