摘要:
An image forming apparatus so composed that it can be furnished with a plurality of developers, can change the developer opposed to the photosensitive body by integrally moving the corresponding developers and can compensate for the position of the corresponding developer at the compensating position thereof while changing developers. Furthermore, in the image forming apparatus, the developers are moved by a motor, the position of the developers is only compensated for when the predetermined compensating position is on a shortest moving path when changing one of the developers to another developer and the developers are always changed through the shortest moving path.

An image forming apparatus is provided with a cooling fan for cooling toner boxes within the apparatus. The outlet of the cooling fan and the toner boxes are connected by flexible tubes, respectively. This makes it possible to connect the cooling fan with the toner boxes even if there is not sufficient space, thereby enabling cooling of the toner boxes.

A compact cleaning apparatus capable of having a good cleaning function is provided with an image forming apparatus. The cleaning apparatus of the image forming apparatus is pivoted inside this image forming apparatus and cleans an intermediate transfer belt or photosensitive drum. This cleaning apparatus is arranged by a casing having an opening for collecting toner stripped from the surface of the object; a cleaning member mounted on one side edge of the opening of the casing and depressed against the surface of the object; and a drive mechanism having a fulcrum located below the opening of the casing, for pivoting the casing in a direction along which the casing is separated from the object. Three shafts cooperate to perform an engagement or removal operation.

A guiding roller unit has a holder to be mounted on a mount, and a guiding roller rotatably supported by the holder. The holder includes a base, two bearings and widening preventing plates attached respectively to the bearing. The base, the bearings and the widening preventing parts are integral to each other. The base is mounted on the mount. The bearings stand from opposite ends of the base and rotatably support the roller. The widening preventing plates extend in directions opposite to facing directions of the bearings. The holder enables the roller to be attached and detached with leading ends of the bearings elastically widened with respect to base ends thereof connected with the base while being detached from the mount, whereas it prohibits widening of the leading ends of the bearings by contacting the mount in response to forces acting in widening directions while being mounted on the mount.
