An image forming apparatus to form an image on a recording material includes an apparatus main body having a first end provided with an opening and having a second end, a fixing device to heat the recording material, an opening and closing member, a drawer unit having a first photosensitive drum, and a transfer device. When being moved from a first inner position inside the apparatus main body to a first outer position outside the apparatus main body through the main body opening, the drawer unit is to be moved in a moving direction intersecting with a rotation axis of the first photosensitive drum, and is to be moved away from the second end. When being moved from a second inner position inside the apparatus main body to a second outer position outside the apparatus main body, the transfer device is moved away from the second end.

Image forming apparatus

An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device a including a belt. When image formation on a recording material is performed, the drawer unit is at a first apparatus main body inner position and the transfer device is at a second apparatus main body inner position. In this drawer unit state, (a) a part of the transfer device is disposed downstream of the drawer unit in a moving direction in which the drawer unit moves from the first inner position to a first apparatus main body outer position, and (b) in a vertical direction, an area where the part of the transfer device is positioned overlaps, at least in part, with an area where the drawer unit is positioned. The transfer device includes a cleaning member to clean the belt and is accommodated in the part of the transfer device.

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.

Image forming apparatus with a transfer device

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.
