An image forming apparatus includes: a main apparatus body having an image forming unit and a discharge tray; and a controller. The main apparatus body includes a conveyance path along which a sheet passed through the image forming unit is conveyed; a discharge path branched from the conveyance path and connected to the discharge tray; and a reconveyance path having a first path different from the discharge path and a second path for conveying the sheet to the image forming unit. In a double-sided printing, if a first sheet has passed through the first path when a forward end of a second sheet arrives at a predetermined position in the conveyance path, the controller conveys the second sheet to the first path and then conveys the second sheet to the second path.

A recording apparatus, comprising: an apparatus body; a recording device that is provided inside the apparatus body and performs recording on a medium; a supporting tray that is switchable between a drawn-out state and a housed state and, when in the drawn-out state, supports the medium that is to be fed toward the recording device, the drawn-out state being a state of being drawn out from the apparatus body, the housed state being a state of being housed in the apparatus body; and a unit that is detachably attached to the apparatus body and includes a reverse roller for reverse the medium, wherein the supporting tray has a portion that is configured to be on a path of attachment and detachment of the unit when in the housed state.

A printer includes a sheet stopper that rotates between a regulating position where a sheet placed in the feeding tray is regulated and a passing position where the sheet placed in a feeding tray is passed through, and an inversion path introduction unit that rotates between a forward-feeding position and a reverse-feeding position of introducing the sheet. The inversion path introduction unit is disposed at the forward-feeding position when a sheet is conveyed in a sheet feeding direction. The inversion path introduction unit is disposed at the reverse-feeding position when a sheet is conveyed in a direction opposite to the sheet feeding direction and the inversion path introduction unit introduces the sheet into an inversion path. The sheet stopper changes the regulating position and the passing position in conjunction with rotation of the inversion path introduction unit.

In an image forming system, a hardware processor controls whether the first sheet is conveyed to an upstream side of the image former via a first conveying path which reverses sides of the first sheet or via a second conveying path which does not reverse the sides of the first sheet as well as the first conveying path, when images are formed on both sides of a plurality of the first sheets by the image former, in order to narrow a space between a plurality of the first sheets.

A recording device includes a recording unit configured to discharge liquid onto a medium to perform recording, a transport unit configured to transport the medium at a position facing the recording unit, a transport unit downstream roller pair located downstream the transport unit in a medium transport path and configured to transport the medium, a restricting roller being a roller configured to restrict movement of a medium back end region upstream the transport unit downstream roller pair in the medium transport path toward the recording unit side, and including a plurality of teeth along an outer periphery thereof, and a guide member being a member configured to support the restricting roller, and guiding the medium.

An image forming apparatus includes an image forming unit, a reversing roller pair, a moving unit, and an obtaining unit. The image forming unit forms an image on a sheet. The reversing roller pair nips the sheet having the image, rotates in a first direction, and then rotate in a second direction and conveys the sheet. The moving unit moves the reversing roller pair. The obtaining unit obtains the sheet length. If a first sheet having a first length is reversed and conveyed, the moving unit moves the reversing roller pair conveying the first sheet in the width direction by a first moving amount. If a second sheet having a second length greater than the first length is reversed and conveyed, the moving unit moves the reversing roller pair conveying the second sheet in the width direction by a second moving amount smaller than the first moving amount.

A first transport unit transports, along a first path, a sheet transported from an image forming unit. A second transport unit transports the sheet along a second transport path branched from a junction with the first transport path. A first cover, when open, holds the sheet transported to an exterior of a housing and, when closed, partially constitutes the second transport unit. A flap is disposed at the junction and, when at a first position, blocks the second transport path and guides the sheet along the first transport path and, when at a second position, blocks the first transport path and guides the sheet along the second transport path. A drive unit moves the flap between the first position and the second position. A moving mechanism moves away from the flap in response to closing of the first cover, and pushes and moves the flap to the second position.
