A sheet conveyance device includes a sheet passage, a first sheet stacker, a second sheet stacker, and a sheet feeder. The first sheet stacker has a bottom and a lift. The sheet feeder includes an opening and a feed roller. The sheet conveyance device includes an assist plate supported to be movable between a first and a second position and an urging member. With the first sheet stacker mounted in an apparatus body, the assist plate moves from the first to the second position against the urging force of the urging member to allow passage of a sheet from the first sheet stacker to the sheet feeder. With the first sheet stacker removed from the apparatus body, the assist plate is urged by the urging member to move from the second to the first position to support the sheet conveyed from the second sheet stacker to the sheet feeder.

An image forming system includes an image forming apparatus including an image forming unit and a fixing unit; a folding processing portion; a pressure-bonding portion; and an input portion capable of selecting a pressure-bonding mode in which a pressure-bonding print prepared by subjecting the recording material to pressure-bonding processing by the folding processing portion and the pressure-bonding portion and capable of selecting a layout of the toner image formed on the recording material. When the pressure-bonding mode is selected, the layout depending on the pressure-bonding mode is selected.

An image forming apparatus includes a main body housing, a main body connector, a fuser having a fuser connector, a power supply board, and a main board. The fuser connector is disposed at a first end section in the main body housing with the fuser attached to the main body housing. The main board is disposed at a second end section opposed to the first end section in the main body housing. The power supply board is connected with the main board via a first connection line disposed close to and along a ceiling surface or a bottom surface in the main body housing, and is connected with the main body connector via a second connection line. The main board is connected with the fuser via the first connection line, the power supply board, the second connection line, the main body connector, and the fuser connector.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a restricting section that restricts bending of the recording medium by coming into contact with the recording medium loaded on the loading surface; and an abutting section that abuts the one end of the recording medium against the supporting section by pushing an upper end of the recording medium opposite to the one end downward, in a state where the restricting section restricts the bending of the recording medium.

A sheet storage device includes a sheet storage, a handle, a cover, and a handle holder. The sheet storage is insertable into and removable from an apparatus body. The handle is for insertion and removal of the sheet storage into and from the apparatus body. The cover is attached in front of the sheet storage in a removal direction of the sheet storage. The handle holder holds the handle on the sheet storage, is disposed between the cover and the sheet storage, and has a restrictor that restricts deformation of the cover toward the sheet storage.

An image forming apparatus includes a housing, a charging roller, an image forming section, a bearing member, a holding member, an urging member, a fixing section, and an unfixing section. A cylindrical image bearing body is attached to the housing. The charging roller comes into contact with the surface of the image bearing body and charges the surface. The image forming section forms an image on the charged surface. The holding member holds the bearing member. The urging member urges the bearing member in a first direction. The fixing section fixes the bearing member in a first position. The unfixing section separates the charging roller from the surface of the image bearing body and positions the holding member in the housing, unfixes the bearing member, moves the bearing member to a second position, and brings the charging roller into contact with the surface of the image bearing body.

An image forming apparatus includes a main body housing, a main body connector, a fuser having a fuser connector, a power supply board, and a main board. The fuser connector is disposed at a first end section in the main body housing with the fuser attached to the main body housing. The main board is disposed at a second end section opposed to the first end section in the main body housing. The power supply board is connected with the main board via a first connection line disposed close to and along a ceiling surface or a bottom surface in the main body housing, and is connected with the main body connector via a second connection line.
