A medium discharging device includes a discharging unit which discharges a medium; and a medium receiving tray which receives the medium discharged by the discharging unit, and is switched between an extended state and an accommodated state, in which the medium receiving tray is provided with a base tray, a main extendeding unit that is accommodated or extended, and at least one sub-extendeding unit that is accommodated or extended, and in which the base tray forms an accommodating space for accommodating at least the one sub-extendeding unit, and is provided with a first protrusion portion protruding toward the accommodating space.

Provided is a disinfection unit and a sheet processing apparatus that can disinfect sheets without affecting the processing of the sheets. The disinfection unit includes: a disinfection part disposed to face a sheet that is being transported; a jacket through which a refrigerant for cooling the disinfection part passes without being leaked on a way; and a refrigerant supply device configured to supply the refrigerant to the jacket.

A sheet feeding apparatus includes a supporting portion, a sheet feeding unit, a side edge regulation plate, a separation unit configured to separate the sheets by blowing air onto the plurality of sheets supported by the supporting portion, a regulation plate position detection unit configured to detect a position of the side edge regulation plates in the width direction, and a control unit configured to execute a separation mode so as to perform an air-blow operation by the separation unit in feeding the sheets by the sheet feeding unit. In the separation mode, in a case where the position of the side edge regulation plate detected by the regulation plate position detection unit does not correspond to size of the sheets supported by the supporting portion in the width direction, the control unit is configured to stop the air-blow operation.

An image forming apparatus includes an apparatus body, a wall face of the apparatus body having an ejection opening from which a sheet conveyed in a first direction is ejected, a sheet support to support the sheet discharged from the discharge opening in the first direction, and a mount to mount the sheet support to the apparatus body. The mount includes an abutting portion including an abutting face that contacts a wall face of the apparatus body, and a projection projecting in a second direction opposite to the first direction from the abutting face. The abutting face extends in a vertically downward direction from the projection, and the projection is fixed to the apparatus body in a vertical direction.

An image forming apparatus is provided including an image forming unit configured to form an image on a print medium, and a printed medium post-processing unit configured to receive and post-process printed media on which an image forming process is completed from the image forming unit. The printed medium post-processing unit selectively comprises one of a first stacker module in which a first amount of post-processed printed media is able to be loaded, and a second stacker module in which a second amount of post-processed printed media is able to be loaded. Therefore, it may be possible to flexibly respond to a loading amount of the printed media necessary for the printed medium post-processing unit.
