An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.

An image forming apparatus includes an image forming unit and a developing separation mechanism. The image forming unit includes an image carrier and a developing device. The developing device includes a developing member and movable in a developing position where the developing member is in contact with the image carrier and a separated position where the developing member is separated away from the image carrier, and is configured to be drawn out from an apparatus main body. The developing separation mechanism includes an arm member configured to interfere with the developing device from a downstream side of a draw-out direction so as to move the developing device from the developing position to the separated position, and to be turned to an upstream side of the draw-out direction by the image forming unit when the image forming unit is drawn out and then be separated from the developing device.

An image forming apparatus includes: a photosensitive member; a developing roller; a contact/separation mechanism configured to switch between a contact state in which the developing roller is brought into contact with the photosensitive member and a separation state in which the developing roller is separated from the photosensitive member; a photosensitive-member motor configured to rotate and drive the photosensitive member; and a control portion. The control portion configured to determine that the contact/separation mechanism is in a failure state in a case where a torque of the photosensitive-member motor is not detected to have changed by at least a predetermined value within a predetermined time after a predetermined reference timing.

A feeding device to feed a conveyed medium stacked on a stacker, includes a first suction unit, a second suction unit, and third suction units. The first suction unit includes a suction chamber; a suction fan to exhaust air from the suction chamber; and a first driver to rotate the suction fan. The suction units are disposed above the conveyed medium stacked on the stacker. The second suction unit includes a rotary fan including a board and a plurality of walls extending from the board; and a second driver to rotate the rotary fan. The second suction unit generates a vortex flow directed to the conveyed medium. The plurality of third suction units is disposed in a direction perpendicular to a conveyance direction of the conveyed medium and attracts ends of the conveyed medium in the direction perpendicular to the conveyance direction.

An image processing apparatus comprises a container which is constituted by a bottom connected with a side wall of the image processing apparatus and extending upwards in the vertical direction at a predetermined angle from the side wall and a side wall section vertically arranged on the bottom, and houses a sheet to be processed in a space formed by the side wall of the image processing apparatus and the side wall section; and a pickup section configured to make a roller enter to the inside of the container when the pickup section executes a pickup operation for conveying the sheet to be processed to a main body section of the image processing apparatus and make the roller located inside the image processing apparatus when the pickup section does not execute the pickup operation.

A sheet feeding apparatus includes a supporting portion and a feeding unit. The supporting portion supports a sheet and is capable of being drawn out from and being attached to an apparatus body. The feeding unit is provided in the apparatus body and includes a feeding portion, a conveyance portion, a separation unit, and a guide member. The feeding portion feeds the sheet supported by the supporting portion. The conveyance portion conveys the sheet. The separation unit forms a separation nip with the conveyance portion and is detachable from the feeding unit. The guide member includes a guide surface and a lower surface. The guide surface guides the sheet to the separation nip. The lower surface is provided below the guide surface and includes an exposing portion exposing at least a part of the separation unit.

A sheet feeding apparatus is provided with a pick-up roller that contacts sheets loaded on a load tray to pick up, a paper feed roller that feeds a picked-up sheet, and a separation roller brought into press-contact with the paper feed roller to separate the sheet, where the sheets are separated from the pick-up roller, the separation roller is rotated in a sheet return direction different from a sheet feed direction, and subsequently, the paper feed roller is separated from the separation roller. It is possible to prevent damage to a sheet and sheet jam from occurring in pulling out the load tray loaded with sheets to the front side.

An image forming system includes an image forming apparatus, a sheet laminator, and circuitry. The sheet laminator performs a lamination processing on a two-ply sheet with a sheet, which is conveyed from the image forming apparatus and inserted between two sheets of the two-ply sheet. The circuitry performs a lamination print mode and a shift mode. In the lamination print mode, the sheet laminator performs the lamination processing on the sheet. In the shift mode, a power supply to the image forming apparatus starts and the power supply ends when the power supply reaches a first peak value and is stabilized during a first start-up period. Also, in the shift mode, the power supply to the sheet laminator starts and the power supply ends when the power supply reaches a second peak value and is stabilized during a second start-up period shifted from the first start-up period.

An image processing apparatus comprises a container mounted on a side wall of the image processing apparatus and comprising a bottom extending upwards in the vertical direction at a predetermined angle from the side wall for supporting an end of a sheet and a wall member vertically arranged on the bottom and forming a space with the bottom, and configured to house a sheet in the space through an opening formed on the upper side of the container; and a pickup unit located adjacent to the bottom of the container and having a pickup roller and configured to move the pickup roller to the inside of the container if a pickup operation for conveying the sheet to the inside of the image processing apparatus is executed, and keep the pickup roller at a waiting position outside of the space of the container if the pickup operation is not executed.

A conveying roller has a rotary shaft portion, a roller supporting member, and a roller member. The rotary shaft portion is extendable/contractible. The roller supporting member has an interior space. The roller member is supported on the outer circumferential surface of the roller supporting member. The rotary shaft portion includes first and second shafts. The first shaft has one end part inserted into the interior space, and is movable axially relative to a first side surface. The first shaft has a regulating portion displaceable between a permitting position where the regulating portion permits the movement of the first shaft in the insertion direction relative to the roller supporting member without interfering with a rim of an opening and a restricting position where the regulating portion restricts the movement of the first shaft in the insertion direction relative to the roller supporting member by interfering with the rim.
