Image forming apparatus including a controller that controls superposition of a correction toner image

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.

主权项

1. An image forming apparatus comprising:
an image forming section that transfers a toner image to a transfer target and that includes
a plurality of developing units that include a first developing unit and at least one second developing unit and that each include
an image holding body that has an outer circumferential surface and that is rotated, anda developing roller that holds developer, that faces the image holding body, and that is rotated in an opposite direction to a rotating direction of the image holding body such that an outer circumferential speed of the developing roller is higher than an outer circumferential speed of the image holding body, and a controller that controls the image forming section so that, when a low-area-coverage portion having a low area coverage and a high-area-coverage portion having a higher area coverage than the low area coverage 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.
