Abstract: An image forming apparatus includes a casing in which multiple units are disposed. The casing has a front wall having a first opening and a stepped wall having a second opening. In the casing, an exposure unit is disposed in front of an image forming unit, above the first opening, and above a sheet loading section, and a fixing unit is disposed above the image forming unit. The exposure unit is disposed with a first gap between the exposure unit and the image forming unit, and the fixing unit is disposed with a second gap between the exposure unit and the image forming unit. The first gap and the second gap constitute a ventilation channel for distributing outside air flowing into the casing through the first opening to the second opening.

Abstract: A sheet storage device includes a sheet positioning member that is movable in a first direction, and positions a sheet by abutting on a side end portion of the sheet at a side in the first direction. The sheet positioning member includes a moving body, an abutting portion, a first and a second biasing member, and a bias removing portion. The moving body is configured to move in the first direction. The abutting portion is supported by the moving body to be movable in the first direction and configured to abut on the side end portion when the sheet positioning member positions the sheet. The first biasing member biases the abutting portion toward the side end portion. The second biasing member biases the abutting portion against a biasing force of the first biasing member. The bias removing portion removes a bias applied by the second biasing member.

Abstract: A sheet positioning member is provided on a sheet placing surface in such a way as to be movable in a predetermined first direction. The sheet positioning member includes a moving body, an abutting portion, an operation member, and a cam portion. The moving body moves in the first direction on the sheet placing surface. The abutting portion has an abutting surface that abuts on the side end portion when the sheet positioning member positions the sheet. The operation member is supported by the moving body so as to be pivotable around a support shaft that extends in the first direction, on a side of a back surface of the abutting portion. The cam portion displaces the abutting portion toward the side end portion by being pressed by the operation member in response to a pivoting operation of the operation member.

Abstract: The sheet feeding cassette includes a cassette frame, a first lift plate and a second lift plate. The cassette frame includes a bottom plate and side plates extending in the feeding direction. The bottom plate and the side plates form a sheet placement space. The first lift plate is disposed on the bottom plate, configured to rotate up and down around a first axis extending along a width direction perpendicular to the feeding direction, and configured to lift a leading end portion in the feeding direction of the sheet. The second lift plate is configured to rotate up and down around a second axis extending along the feeding direction and to lift a side end portion along the feeding direction of the sheet.
