An image forming apparatus includes a housing, a toner image forming portion, a foil transfer unit, a sheet tray, and a discharge portion. The toner image forming portion is provided in the housing and configured to form a toner image on a sheet. The foil transfer unit is configured to superpose a foil with a surface of the sheet. The sheet tray is installable in the housing in an inserting direction and configured to accommodate a sheet to be supplied to the toner image forming portion. The first discharge portion is configured to discharge the sheet from the foil transfer unit to the outside of the housing in a discharging direction opposite to the inserting direction. The second discharge portion is configured to discharge the sheet from the toner image forming portion to the outside of the housing without passing through the foil transfer unit in the discharge direction.

An image forming apparatus includes a paper discharging tray and a paper detection part disposed at an upstream end of the paper discharging tray in a paper discharge direction. The paper detection part includes a base end member provided rotatably around a first axis extending in a direction perpendicular to a paper discharge direction and a tip member pivoted to the base end member to rotate around a second axis parallel to the first axis, and extending downwardly to incline toward an upstream side of the paper discharge direction in a state where the base end member is not subjected to pressure from the paper being discharged. The base end member is disposed to face a discharge opening when being at the reference position, and the image forming apparatus stops discharging paper from the discharge opening when the base end member rotates by a predetermined threshold or more with respect to the reference position.

A turnable sheet stopper blocks and passes a sheet conveyed on a sheet guide, and includes a proximal portion, a distal portion connected to the end of the proximal portion, and a folding mechanism that connects the distal portion to the proximal portion. The sheet stopper transitions between first and second positions. In the second position, the proximal and distal portions integrally turn to the downstream side in the sheet conveyance direction to allow the sheet to pass. The sheet stopper transitions from the second position to a third position when a user draws out the sheet from an upstream side. In the third position, the distal portion folds toward the upstream side to allow the sheet to be drawn out. During transition from the second position to the third position, the edge of the distal portion is located on or away from an outer surface of the sheet guide.

A sheet post-processing apparatus includes a first regulating device regulating a position of a sheet bundle, by contacting to an end part of the sheet bundle conveyed in a conveying direction by a conveying device and stacked on a stacking device in a direction intersecting with the conveying direction; a second regulating device regulating a position of the sheet bundle in the conveying direction, by contacting to an end part of the sheet bundle stacked on the stacking device in the conveying direction; a first binding device configured to move from one side to another side of the sheet post-processing apparatus and from the other side to the one side by moving in the intersecting direction, and configured to bind a corner part of the sheet bundle using a staple, and a second binding device configured to bind a corner part of the sheet bundle without a staple.

A sheet discharge device includes a sheet discharge portion, a sheet loading portion, and a stopper mechanism. The stopper mechanism includes a first stopper supported pivotably to a first retraction position and a first restriction position, a second stopper that is movable to a first position at which the second stopper is housed along a downstream end part of the sheet loading portion and a second position apart from the first position to a downstream side in a sheet discharge direction and is supported pivotably to a second retraction position and a second restriction position, and a link mechanism connecting the first stopper to the second stopper. When the second stopper is disposed at the first position, the first stopper is disposed at the first restriction position, and when the second stopper is disposed at the second position, the first stopper is disposed at the first retraction position.

An image forming apparatus includes an upper guide unit fixed to the image forming apparatus and configured to guide an upper surface of the sheet discharged by a roller pair, a stack unit provided at a position recessed from an upper exterior unit of the image forming apparatus, and an operation unit including a display unit. The discharged sheets are stacked on the stack unit. The upper guide unit extends more to a downstream side in the discharge direction than the roller pair. The operation unit and the upper guide unit each have a portion overlapping with each other. When viewed in an axial direction of the roller pair, the operation unit and the upper guide unit are arranged at positions through which a straight line orthogonal to a plane passing through axes of rollers of the roller pair and passing through a nip portion of the roller pair passes.

An image forming apparatus for forming an image on a recording medium, the image forming apparatus includes a discharge tray for supporting the recording medium, an internal unit disposed inside the apparatus main body, and a door serving as a part of outer surface members of the apparatus main body, the door being opened and closed to expose and cover an inside of the apparatus main body to the outside, wherein, by opening of the door, a fixing member that fixes the discharge tray to the apparatus main body is exposed to the outside, and removing of the fixing member from the apparatus main body allows the discharge tray to be detached from the apparatus main body without removing the outer surface members other than the door, and wherein detaching of the discharge tray from the apparatus main body allows the internal unit to be accessed.

A processing system includes a processing apparatus, a feeding apparatus, an ejection apparatus, and circuitry. The processing apparatus includes a processing device to execute a process on each of objects including a first object and a second object. The feeding apparatus feeds the objects to the processing apparatus. The ejection apparatus ejects the objects sent from the processing apparatus. The ejection apparatus includes an ejection purge portion to receive the second object traveling in the ejection apparatus. The circuitry sets whether to permit ejection of the second object not jammed to the ejection purge portion in case of a jam of the first object in the processing system. The circuitry causes the second object to be ejected to the set ejection purge portion, in response to detection of the jam of the first object.

An image forming apparatus of the present invention includes: a body; a developing cartridge having a memory medium and a developer bearing member; a tray including a frame which is movable between a housed position and a drawn-out position and has side portions extending in the moving direction and to which the developing cartridge is attachable, an image bearing member that faces the developer bearing member when the developing cartridge is attached, a tray-side metal terminal provided on the side portion and electrically connected to the memory medium when the cartridge is attached, and a tray guide portion extending along the moving direction; a body-side metal terminal that faces the tray-side metal terminal when the tray is housed, wherein the tray-side metal terminal is provided below the tray guide portion.

A post-processing device includes an output unit that outputs a medium; a stacking unit on which the medium that is output is stacked; and a blow-out unit that is disposed below the output unit and that blows gas toward the medium that is output, wherein an amount of the gas blown is adjusted in accordance with a type of the medium.
