Abstract: A sheet feeding device includes a sheet stacking member, a feeding member provided above the sheet stacking member, and a lifting member to lift up and down the sheet stacking member. An accommodating unit for accommodating the sheet is provided with a supporting frame for supporting the sheet stacking member. A restricting member restricts a position of the sheet stacking member. Movement in a lifting down direction of the sheet stacking member is restricted by the restricting member when the restricting member is attached to the supporting frame in a state in which the sheet stacking member is lifted up to a predetermined position.

Abstract: An image forming apparatus includes a fixing device to heat a recording material at a use position, an opening and closing member, and a drawer unit. In a state where the fixing device is at the use position, part of the fixing device is located in a space for the drawer unit to pass through when moved from a first inner position to a first outer position so that movement of the drawer unit from the first inner to the first outer position is restricted. The fixing device is retracted from the use position to a retracted position so that the movement of the drawer unit from the first inner to the first outer position is allowed. Part of the fixing device at the retracted position is at a position higher than a position of an upper cover portion of the opening and closing member at a closed position.

Abstract: An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device including a belt. The drawer unit includes a first cartridge, a support member to which the first cartridge is detachably attached, and a first photosensitive drum disposed on the support member or the first cartridge. The drawer unit is moved to a first inner position inside the apparatus main body and to a first outer position outside the apparatus main body. The transfer device is moved to a second inner position inside the apparatus main body and to a second outer position outside the apparatus main body. The belt contacts the first photosensitive drum with the transfer device at the second inner position. The transfer device is moved from the second inner to the second outer position when the drawer unit is moved from the first inner to the first outer position.

Abstract: Provided is a sheet feeding apparatus including a sheet storing tray for loading sheets, an apparatus main body to which the sheet storing tray is slidably attached, and a restriction mechanism that restricts a position of the sheet storing tray. The restriction mechanism includes an engagement portion provided in the apparatus main body and a stopper member that is provided in the sheet storing tray and engages with the engagement portion. The stopper member is configured so as to be movable in a crossing direction crossing a direction in which the sheet storing tray slides and determines a position in the crossing direction of the sheet storing tray with respect to the apparatus main body.
