A sheet processing apparatus of the invention has: an ejecting unit that is capable of receiving a sheet on which a toner image has been heated and fixed, and ejecting the sheet for a predetermined normal ejecting time; and a processing unit that processes the sheet ejected by the ejecting unit according to obtained sheet information, wherein the ejecting unit ejects the sheet for an ejecting time longer than the normal ejecting time.

Sheet processing apparatus that pauses sheet ejection to prevent a sheet from adhering to a previous sheet

Sheet processing apparatus and image forming apparatus

A sheet post-processing unit which includes a sheet stacking portion, a sheet conveying portion, an intersectional moving device, a vertical moving device, an intersectional regulating member, and a controller. The sheet stacking portion stacks sequentially discharged sheets. The sheet conveying portion conveys each sheet stacked on the sheet stacking portion. The intersectional moving device moves the sheet conveying portion in a direction intersecting with a sheet discharging direction. The vertical moving device moves up and down the sheet conveying portion in a vertical direction. The intersectional regulating member aligns each sheet by contacting an edge of each sheet. The controller controls the intersectional moving device and the vertical moving device to move the sheeting conveying portion, and to press-contact the sheet conveying portion to an upper surface of a sheet and separate it from the sheet.

Sheet post-processing unit and image forming apparatus

The invention is to provide a sheet treating apparatus achieving a space saving and enabling easy identification of an output mode of sheets. The sheet treating apparatus of the invention for treating sheets after image formation is accommodated in a space formed in an image forming apparatus, and includes plural sheet stacking devices which stack treated sheets, and a lifting and lowering device which independently lifts and lowers the plural sheet stacking devices.

Sheet treating apparatus and image forming apparatus provided therewith

A sheet post-processing unit usable in an image forming apparatus includes a sheet stacking device; a sheet conveying device including at least one roller rotatably supported by an arm movably and vertically rockingly supported, an actuator for moving the arm capable of selectively conveying each sheet to be discharged and of separating from the sheet by moving in a vertical direction; a control section for setting a moving distance of the intersectional moving device corresponding to a size of each sheet to be discharged; and a sheet clamping device. The roller abuts an uppermost sheet among sheets stacked on the sheet stacking device and an intersectional moving device moves the roller in the intersecting direction by a moving distance corresponding to the sheet size set by the control section to hit against and align the uppermost sheet with an upstream side regulating member and an intersectional regulating member.

There is provided a sheet post-processing unit and image forming unit, which is capable of stably conveying sheets discharged one after another to a tray to form a bundle of sheets and to staple the bundle. A sheet conveying means is provided for selectively conveying the sheet to be discharged in the downstream and upstream directions of the sheet discharging direction, as well as moving the sheet in a direction intersecting the sheet conveying direction, and which is capable of moving up and down to be contactable with, and detachable from, the sheet.

A sheet processing apparatus including a first sheet stacking portion for stacking sheets thereon, a second sheet stacking portion provided downstream of the first sheet stacking portion with respect to a sheet conveying direction, a sheet holding device for holding the sheets stacked on the first sheet stacking portion, and a holding device moving device for moving the sheet holding device between a holding position for holding the sheets and a discharging position provided downstream of the holding position in the sheet conveying direction, wherein the discharging position has a predetermined distance upstream from a stop position in which the sheet holding device moved to a downstream side with respect to the sheet conveying direction by the holding device moving device is stopped to an upstream side.
