An image forming apparatus, having a housing with an opening, an image forming unit, a path to guide a recording medium toward the opening, a reversible roller disposed in the path, and an intermediate reversible roller disposed between the image forming unit and the reversible roller, is provided. A rotating direction of the reversible roller is switchable between a first rotating direction and a second rotating direction opposite from the first rotating direction. A circumferential speed of the reversible roller is switchable between a predetermined circumferential speed and none. A rotating direction of the intermediate reversible roller is switchable between a third rotating direction and a fourth rotating direction opposite from the third rotating direction. The circumferential speed of the reversible roller in the first rotating direction is reduced to be lower than the predetermined circumferential speed while the intermediate reversible roller is rotating in the third rotating direction.

An image forming apparatus including an image forming portion, a moving portion, a re-conveyance portion, a detection portion, and a control portion is provided. The image forming portion is configured to form an image on a sheet that is conveyed. The moving portion is configured to move the sheet in a width direction. The re-conveyance portion is configured to invert the sheet having the image formed on a first surface thereof convey the sheet to the image forming portion again. The control portion is configured to control, based on a detection result of the detection portion, the moving portion to move the sheet in the width direction such that the center of the image formed on the first surface in the width direction and a center of the image to be formed on the second surface in the width direction coincide.

A banknote deposit and withdrawal apparatus causes a control section to function as an inserted medium counting unit, a normal medium counting unit and an abnormal mediums number calculation unit. The normal medium counting unit again feeds out and conveys banknotes from the banknote deposit and withdrawal section to the verification section in a quantity corresponding to the number of inserted banknotes, conveys abnormal banknotes that are verified as abnormal by the verification section to the banknote deposit and withdrawal section together with following banknotes but conveys normal banknotes that are verified as normal by the verification section to the temporary holding section and retains the normal banknotes therein, and counts a number of normal banknotes. The abnormal mediums number calculation unit subtracts the number of normal banknotes from the number of inserted banknotes to calculate an abnormal banknotes number.

An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.

A reversing roller pair is controlled such that, when an abnormality occurs during the conveying of a sheet, the sheet is conveyed in a forward direction by the reversing roller pair, and is controlled to continue conveying until a state where the final sheet among the sheets conveyed in the forward direction is detected by a first detection portion, and subsequently to stop in a state where the final sheet is nipped by the reversing roller pair.

An image forming apparatus includes: one paper cassette configured to accommodate a paper sheet; an image forming section provided above the paper cassette to form an image on the paper sheet; a main conveying path configured to convey the paper sheet; and a reverse conveying path configured to reverse the paper sheet, wherein the reverse conveying path includes: a first reverse conveying path provided side by side with the paper cassette to extend vertically; a second reverse conveying path configured to connect from the first reverse conveying path and extend below the paper cassette; a guide plate configured to open and close the first reverse conveying path and release pressure of a pair of paper conveying rollers; and an entry restricting unit provided at a boundary point between the first reverse conveying path and the second reverse conveying path to open and close a conveying course of the paper sheet.

A sheet feeding apparatus includes a first drive roller and a second drive roller disposed downstream of the first drive roller and configured to rotate at a peripheral speed greater than a peripheral speed of the first drive roller. The first drive roller includes a drive shaft and a roller portion. The roller portion is configured to contact the sheet and is movable relative to the drive shaft in an axial direction and a rotation direction of the drive shaft. One of the drive shaft and the roller portion of the first drive roller includes a protrusion protruding toward the other one of the drive shaft and the roller portion. The other one of the drive shaft and the roller portion of the first drive roller includes a recessed portion. The recessed portion includes a peripheral wall that defines an opening such that the protrusion is positioned in the opening.
