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 medium conveying apparatus includes a housing including an accommodation portion provided with a guide portion at an end portion in a width direction, a tray accommodated in the accommodation portion so as to be pulled out, and including a placing surface for placing an ejected medium, and an engaging portion provided on a side surface of the tray, to engage the guide portion. The guide portion includes a pair of rails inclined upward and having a predetermined width. The engaging portion includes two protrusions provided so as to slide between the pair of rails and located apart from each other by a predetermined distance. By locating the two protrusions between the pair of rails, the tray is positioned at a predetermined position with respect to the housing with a front end portion of a downstream side in the medium ejecting direction located upward.

An image formation air blowing device includes an outlet and an airflow control portion. The outlet blows out an airflow toward a target space on a discharge table to which a sheet with an image formed thereon by an image forming portion is discharged. The airflow control portion controls a direction of the airflow at least in a horizontal plane in the target space.

An image forming apparatus includes a photosensitive drum, a development device, a fixing device, an apparatus main body, and a fan including a rotating shaft that extends in a longitudinal direction of the photosensitive drum and a blade around the rotating shaft. The development device develops a toner image on the photosensitive drum. The fixing device fixes the toner image from the photosensitive drum to a recording material. The apparatus main body is provided with a discharge port from which the toner-fixed recording material is discharged. A length of the fan rotating shaft in the longitudinal direction is longer than a diameter of a rotational trajectory of the blade. The fan is provided on a downstream side of the fixing device in a discharge direction in which the recording material is discharged from the discharge port and overlaps a part of the development device when viewed in a vertical direction.

An image forming apparatus includes a main body that includes a photosensitive member on which an electrostatic latent image is formed and a development unit configured to develop the photosensitive member with toner. The main body is configured to discharge a recording material on which an image is formed with the toner onto a discharge tray. The image forming apparatus also includes a toner supply port on which a supply container is mounted to supply toner to a toner containing portion of the development unit. The image forming apparatus further includes a non-contact communication portion including an antenna and configured to receive a signal for user authentication. The discharge tray, the toner supply port, and the non-contact communication portion are provided at an upper portion of the main body. The non-contact communication portion is provided outside the discharge tray when the main body is viewed from above.

A sheet conveying device can selectively execute a first conveyance process of conveying sheets on a first tray and discharging the sheets onto a second tray, a second conveyance process of conveying the sheets on the first tray and discharging the sheets onto a third tray, or a third conveyance process of conveying the sheets on the third tray and discharging the sheets onto the second tray. A control device records conveyance history information indicating by which conveyance processes each of the sheets on the first tray has been conveyed in a storage device. Furthermore, the control device causes the sheet conveying device to sequentially select the first conveyance process or the third conveyance process for each of the sheets based on the conveyance history information and execute the selected process.

An image forming apparatus includes an image formation unit, a casing a sheet discharge unit, a supporting portion, a first electric board, a second electric board, and a connecting cable. The first electric board is disposed such that the first electric board does not overlap the supporting portion in a width direction when viewed in the vertical direction. The second electric board is disposed such that the second electric board does not overlap the supporting portion in the width direction when viewed in the vertical direction. The second electric board is disposed on a same side in the width direction as the first electric board with respect to the supporting portion when viewed in the vertical direction. At least a part of the second electric board overlaps the first electric board in the vertical direction and the sheet discharge direction when viewed in the width direction.

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.

A sheet discharging apparatus includes a discharging portion configured to discharge a sheet, a supporting portion configured to support the sheet discharged by the discharging portion, a lifting portion configured to lift and lower the supporting portion, a transmissive sensor configured to output an output signal that changes in accordance with a position of an upper surface of the sheet supported by the supporting portion, a reflective sensor configured to output an output signal that changes in accordance with the position of the upper surface of the sheet supported by the supporting portion, and a controller configured to control the lifting portion and including a first determining portion configured to determine whether or not sheet detection by the transmissive sensor is possible and a second determining portion configured to determine whether or not sheet detection by the transmissive sensor is needed.
