An image forming apparatus includes an image forming portion, an image input portion, a transfer unit, a transfer voltage power supply, and a control portion. The transfer unit includes a transfer roller having a metal shaft and an elastic layer laid around an outer circumferential face of the metal shaft to form a transfer nip by keeping the elastic layer in pressed contact with an image carrying member, and transfers a toner image formed on the image carrying member to a recording medium as it passes through the transfer nip. The transfer unit includes, as the transfer roller, a first roller, and a second roller having a larger axial-size elastic layer compared to the first roller. The control portion arranges the first or second roller opposite the image carrying member according to width-direction sizes of the recording medium and image data fed to the image input portion.

A positioning structure includes a positioning aiding member attached to a horizontal beam of a sheet feeder and having a positioning hole formed at an opposed portion thereof opposed to the horizontal beam. The positioning aiding member has a guide part that, when an image forming apparatus is installed onto a top of the sheet feeder, guides a horizontal beam of the image forming apparatus such that a positioning hole formed in a lower surface of the horizontal beam of the image forming apparatus approaches a first positioning pin coupled with the positioning aiding member as viewed in an extending direction of the horizontal beam of the sheet feeder.

An image forming apparatus includes a stacking tray, a control unit, an alignment member and a supporting mechanism. The control unit performs a rotational sorting. An alignment member includes a leading end wall coming into contact with a leading edge of a portrait sheet stack, a pair of first side walls coming into contact with both side edges of the portrait sheet stack and a leading edge of a landscape sheet stack, and a pair of second side walls coming into contact with both side edges of the landscape sheet stack and aligning the portrait sheet stack and the landscape sheet stack. The supporting mechanism supports the alignment member so as to be movable in an alignment position where the alignment member protrudes from an upper face of the stacking tray and in a retracting position where the alignment member retracts from the upper face of the stacking tray.

Image forming apparatus

An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.
