In an image forming apparatus, a sheet is guided into a first conveyor path or a second conveyor path selectively when a first cover is in a closed position, and is ejected onto the first cover when the first cover is in an open position. Upon power-up, a controller causes a first conveyor roller to rotate but if the first cover is in the open position, when a sheet sensor detects a sheet, the controller does not cause a second conveyor roller to rotate, and causes a flapper to swing from a first position to a second position, and when a front end of the sheet reaches a position downstream of an upstream end of the flapper in a conveyance direction of the sheet conveyed by the first conveyor roller, the controller causes the flapper to swing from the second position to the first position.

Provided is an image forming apparatus, including; an imaging forming unit for forming a toner image on one surface of a recording material; a fixing unit that includes a heating unit and heats and fixes the toner image formed on the one surface; a discharging unit for discharging the recording material, on which the toner image is fixed, to a discharged paper tray; and a guide member that is disposed between the fixing unit and the discharging unit and forms a recording material conveying path for conveying the recording material from the fixing unit to the discharging unit. On the guide member, a blowing port to send air to the recording material conveying path and a suction port to suck air from the recording material conveying path are disposed on a same surface so as not to cross over the recording materials.

An image forming apparatus includes a single fan, a first air outlet port disposed so as to supply air sent from the fan to an image surface of the sheet, a second air outlet port disposed so as to supply the air sent from the fan to a surface opposite to the image surface of the sheet, and a control unit configured to control the fan. The control unit includes a first mode of controlling a rotational speed of the fan at a first rotational speed in a case where the sheet is not present in a position facing the first air outlet port and control the rotational speed of the fan at a second rotational speed lower than the first rotational speed in a case where the sheet is present in the position facing the first air outlet port.

An image forming apparatus includes an image forming portion, a fixing portion configured to heat and press the sheet conveyed from the image forming portion while nipping and conveying the sheet by a first nip portion to fix toner image to the sheet, a folding portion configured to fold the sheet, and a bonding portion configured to heat and press the sheet folded by the folding portion while nipping and conveying the sheet by a second nip portion to bond the sheet by powder adhesive. A peak value of pressure that the second rotary member pair applies to the sheet in the second nip portion is greater than a peak value of pressure that the first rotary member pair applies to the sheet in the first nip portion.

A first guide member guides a sheet from a sending roller pair to a discharge port. A second guide member is disposed above the first guide member such that an upstream end of the second guide member in a sheet discharge direction overlaps the first guide member, and forms an upper partition of a discharge path in an area extending from a position above an end of the first guide member to a position of a discharge roller pair. The second guide member guides the sheet to the discharge roller pair. A cooling fan blows air from below the discharge path toward a lower surface of the second guide member. The lower surface of the second guide member is formed convexly curved upward when viewed in a width direction intersecting the sheet discharge direction. The lower surface of the second guide member guides air toward the first guide member.

An image forming system including: a reading unit configured to read, through a transparent member, an image on a first sheet conveyed by a conveyance unit; an opposed member provided opposite to the reading unit with respect to the transparent member, the first sheet passing through a gap between the opposed member and the transparent member; and at least one processor configured to control, based on the image read by the reading unit, a geometric characteristic of an image to be formed on a second sheet by an image forming portion, and control a changing unit to change the size of the gap to a first size when the thickness of the first sheet is a first thickness, and to a second size larger than the first size when the thickness of the first sheet is a second thickness larger than the first thickness.

A sheet discharge device includes a discharge unit including a drive roller, to be rotated by a drive source driving force, a driven roller to be driven by the drive roller, and a static elimination unit located downstream from the discharge unit in a sheet discharge direction. The discharge unit discharges a sheet out of a discharge nip portion between the drive roller and the driven roller. The static elimination unit eliminates electric charge from the sheet to be discharged. The static elimination unit includes a static elimination cloth having electroconductive fiber and facing the sheet to be discharged and includes a support member supporting the static elimination cloth. The static elimination cloth is located so that a static elimination plane of the static elimination cloth, constituting a virtual plane facing the sheet, is substantially parallel to a virtual tangent line extending from the discharge nip portion.

A sheet discharge apparatus includes a stack portion, a reversing unit configured to reverse a reversing sheet, a support member configured to support a lower surface of the reversing sheet, a discharging unit configured to discharge a discharging sheet from the apparatus body, a pivotable member arranged above the stack portion, and a detector configured to output a detection signal that changes according to a pivot angle of the pivotable member. When viewed in a sheet width direction perpendicular to the first conveyance direction, a pivoting locus in which the pivotable member pivots overlaps the support member.

A sheet discharging apparatus includes a sheet supporting portion supporting a sheet discharged out of a nip portion nipping the sheet and a guide portion provided opposed to an upper surface of the sheet fed out of the nip portion. The guide portion includes a fixed restricting portion restricting a rear end of the sheet with respect to a sheet discharging direction to moving upward away from an extension line in a sheet discharging direction of the nip portion after passing through the nip portion.

A movable-member supporter includes: a first support member that includes a first support plate, a first guide unit provided at the first support plate, and a first connection section, the first guide unit guiding movement of a movable member and having one end that extends to one side surface of the first support plate, the first connection section being provided at the one side surface of the first support plate; and a second support member that includes a second support plate, a second guide unit provided at the second support plate, and a second connection section, the second guide unit guiding movement of the movable member and having one end that extends to one side surface of the second support plate, the second connection section being provided at the one side surface of the second support plate and being connected with the first connection section of the first support member.
