摘要： An image forming apparatus includes an image forming unit, a sheet conveyor and a main body that houses the image forming unit and the sheet conveyor. An operating unit is mounted to a front cover that can move between a closed position to cover an anterior side of the main body and an open position to expose a part of the main body. A retention mechanism retains the front cover at the closed position. The retention mechanism has a lock and a release. The lock is supported by one of the apparatus main body and the front cover and is selectively engageable with and detachable from the other. The release releases engagement of the lock, and is installed posterior to the operating unit in a region facing a back surface as viewed from an opening and closing direction of the front cover.

摘要： A cleaning device according to the present invention has first seals and a second seal adhered so as to partly overlap each other for sealing a space between a housing of the cleaning device and the surface of a photoreceptive member. The first seals include seal bases and a flocked sheet layered on the seal bases. The portion of the seal base where the second seal overlaps is made smaller in thickness than the portion of the seal base where the second seal does not overlap. Therefore, no step is formed in the overlapped portion, thereby preventing toner leakage.

摘要： Disclosed is a sheet transport device for use in an image forming apparatus in which one surface of a guide member and one surface of a first counterpart member define a first sheet transport path, and the opposite surface of the guide member and one surface of a second counterpart member define a second sheet transport path. The second counterpart member is pivotally supported on a main body of the image forming apparatus to be selectively set to a closed position for defining the second sheet transport path and an opened position for exposing an interior of the second sheet transport path. The guide member is pivotally supported on the main body of the image forming apparatus to be selectively set to a closed position for defining the first sheet transport path and a closed position for exposing an interior of the first sheet transport path. The sheet transport device has retaining means for retaining the guide member at the closed position. The guide member is retained at the closed position when the second counterpart member is set to the opened position by the retaining means.
