Abstract: An image forming apparatus includes plural image holding bodies that are provided for respective colors of toners and hold toner images having the respective colors, an intermediate transfer body onto which the toner images having the respective colors held by the plural image holding bodies are transferred, a waste toner collection unit that collects toners remaining on the intermediate transfer body as a waste toner in a case where the toner images having the respective colors transferred onto the intermediate transfer body are transferred onto a recording material, a waste toner developing unit that uses the waste toner collected by the waste toner collection unit to develop a toner image on an image holding body of the plural image holding bodies or the other image holding body of the plural image holding bodies, and a control unit that performs a control to cause the waste toner developing unit to develop the toner image in a case where a predetermined condition about a ratio of a waste toner having each

Abstract: An image forming apparatus includes a main assembly including an image forming portion configured to form an image on a sheet; a front cover mounted on a front side of the main assembly and configured to expose the image forming portion by being rotated from above toward below about a rotational axis crossing a vertical direction; a fixing portion configured to fix a position of the front cover in an open state; an exchange unit detachably mountable to the image forming portion in the open state of the front cover; and a projecting portion provided above the front cover in the vertical direction and configured to project information on exchange of the exchange unit onto an inner surface of the front cover in the open state when the exchange unit is to be exchanged.

Abstract: An image forming apparatus includes a main assembly, a first openable portion provided on a first side of the main assembly, a second openable portion provided on a second side of the main assembly, a single projector portion, a first projecting portion configured to project the image from above the first openable portion onto a projection object provided on the first side or onto the first openable portion when the first openable portion is open, and a second projecting portion configured to project the image from above the second openable portion onto a projection object provided on the second side or onto the second openable portion when the second openable portion is open.

Abstract: An image forming apparatus and method for controlling an image forming apparatus is provided. The image forming apparatus includes a detecting unit, a projecting unit, and a control unit. The detecting unit is configured to detect an event that needs user work on the image forming apparatus. The projecting unit is configured to project an image onto a projection target. The control unit is configured to control projection by the projecting unit. When an event that needs user work on the image forming apparatus is detected, the projecting unit projects an image onto a projection target so that a target portion of the user work can be identified and also projects an instruction image for performing the user work.
