There is provided a recording apparatus with which it is possible to reduce an occupied space to a small size in a configuration of including a mounting unit and a receiving unit.

A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.

A sheet housing apparatus including a housing unit, which houses a sheet to be discharged from a discharging opening of a printer, and a pair of housing-side feet disposed on both sides, in a width direction, of the sheet housing apparatus. The sheet housing apparatus can be combined with the printer. The printer includes a pair of body-side feet disposed on both sides, in the width direction, of the printer. In a state in which the sheet housing apparatus is combined with the printer, the body-side feet and the housing-side feet are arranged not to overlap with each other in the width direction.

An image forming apparatus is provided with: an apparatus body; a photosensitive member; a developing cartridge configured to have a developer supporting body; a cleaner configured to collect developer remaining on the photosensitive member; and a waste developer container configured to contain developer collected by the cleaner. The apparatus body is configured to have an installment passage, through which the developing cartridge passes when the developing cartridge is installed into and removed from the apparatus body. The waste developer container is configured to be movable between a first position at which at least a part of the waste developer container is located within the installment passage and a second position at which the waste developer container is located away from the installment passage.

A cabinet structure includes multiple cover members configured to spatially partition an inside from an outside of a cabinet, and a clearance communicating between the inside and the outside of the cabinet is left between two cover members, the two cover members being adjacent to each other, of the cover members, and a passage defined by the clearance and leading from the inside to the outside of the cabinet through the clearance has a shape with multiple bends.
