An image forming apparatus includes drum shafts supported by a main body, drum cartridges insertable and removable in an axial direction, a regulation side plate having bearings, a projecting portion provided to one of the regulation side plate and the main body, a fitting portion, and an urging force imparting portion. The urging force imparting portion is provided to the regulation side plate in an array direction of the bearings to impart an urging force that urges the regulation side plate toward the main body. At least a part of the urging force imparting portion is provided at a position for imparting the urging force on, with respect to the bearings, a side opposite to a position at which one of the projecting portion and the fitting portion is provided, in a direction orthogonal to the array direction of the bearings and the axial direction of each drum shaft.

Image forming apparatus

An image forming apparatus includes a transfer unit for which, when inclined, leakage of a liquid developer can be suppressed. The transfer unit includes an intermediary transfer belt onto which the liquid developer is transferred and which rotates. A supporting unit is capable of holding the transfer unit at a first position. A rotation holding portion is capable of holding the transfer unit at a second position inclined from the first position relative to the supporting unit. A cleaning roller is capable of removing the liquid developer on the intermediary transfer belt. A cleaning container is supported by the supporting unit irrespective of rotation of the transfer unit and is capable of collecting the liquid developer removed by the cleaning roller.

Image forming apparatus having removable transfer unit

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.

Image forming apparatus including image projector

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.
