The sheet stacking-aligning apparatus or the sheet processing apparatus includes a substantially horizontal stacking tray, a rear end aligning unit for aligning a rear end of a sheet bundle on the stacking tray, and a control unit for controlling an operation of the rear end aligning unit for aligning the sheet bundle when it is in an upstream position of the stacking tray, and the stacking tray is provided substantially horizontally. It is thus made possible to increase the stacking space, thereby increasing the number of stackable sheets and to achieve the alignment of the rear end of the sheet bundle with a simple configuration, thereby improving the stacking-aligning property of the sheet bundle on the stacking tray.

Sheet stacking-aligning apparatus, sheet processing apparatus and image forming apparatus

An image forming apparatus has an image reading portion for reading an image of an original and which is disposed in an upper part of the apparatus, an image forming portion for forming an image on a sheet and which is disposed below the image reading portion with a space portion between the image reading portion and the image forming portion, and a sheet delivery portion disposed in the space portion. There is a taper formed on an edge portion of a bottom of the image reading portion defining the space portion so that a sheet treating apparatus for performing treatment such as sorting, alignment, or stapling of sheets on which the images are formed, is mounted in the space portion.

Sheet treating apparatus, method of mounting sheet treating apparatus, and image forming apparatus

A sheet treating apparatus is mountable in a space portion of an image forming apparatus including an image-forming portion for forming an image on a sheet and an image-reading portion for reading an image of an original. The image-reading portion is disposed above the image-forming portion. The sheet is delivered in the space portion formed between the image-forming portion and the image-reading portion. The sheet treating apparatus includes a connection path unit to be connected with a sheet delivery path for delivering the sheet from the image-forming portion, which connection path unit is mounted in the space portion from the outside of a side surface of the main body of the image forming apparatus, and a sheet-treating unit for performing a treatment of the sheet transported from the connection path unit, which sheet-treating unit is mounted in the space portion from the front side of the main body of the image forming apparatus.

Sheet processing apparatus including a first tray for stacking sheets received from an image forming apparatus, a discharge unit for discharging the sheets from the first tray in a bundle, a second tray for stacking the sheets discharged from the first tray, a discriminating unit for discriminating an attribute of a sheet to be stacked on the first tray, and a controller for selectively controlling whether or not to discharge sheets by the discharge unit in accordance with a discrimination of the discriminating unit.

Sheet processing apparatus for discharging sheets in a bundle

A sheet handling device has a sheet-aligning rotary member with an ejection device for ejecting sheets into a sheet stacking device, a sheet end stopper for holding the end of the sheet stacked in the sheet stacking device; and at least one rotary member for aligning the sheets ejected in the sheet stacking device with the sheet end stopper. The rotary member has an arc-shape outer peripheral surface around a portion of a circumference of said at least one rotary member.

Sheet handling device and image forming apparatus having sheet-aligning rotary member

An image forming apparatus has an image forming section for forming images on sheets, including a sheet processing apparatus disposed to be piled up with a sheet conveying section and the image forming section in a housing of the image forming apparatus. The sheet processing apparatus aligns and binds sheets on which images are formed.

Sheet processing apparatus and image forming apparatus having this

A sheet treating apparatus includes a tray liftable and lowerable while sheets are stacked on the tray. A sheet pressing member is movable between a pressing position in which the sheets on the tray are pressed by the sheet pressing member and a retracted position. A sheet pressing member driving device retracts the sheet pressing member when the tray is lowered and for moving the sheet pressing member to the pressing position when the tray is lifted. A detecting device detects a height position of the sheets on the tray to stop lifting the tray.

A sheet processing apparatus includes a stacking tray for accommodating sheets discharged thereto. A sheet discharging mechanism discharges the sheets to the stacking tray. A moving mechanism reciprocates moves substantially vertically the stacking tray between a first position, which is below the sheet discharging mechanism, and a second position between said first position and the sheet discharging mechanism. A controller controls the moving mechanism to move the stacking tray to the second position when the sheet discharged by said discharging means is discharged through a predetermined distance onto a stacking tray located at the first position.

Sheet processing apparatus with multiple-position stacking tray

The present invention provides a sheet post-treatment apparatus comprising a sheet convey portion having a sheet path and a sheet discharge opening, and a sheet receiving tray portion having a plurality of sheet receiving tray means. Wherein a sheet is transferred between the sheet convey portion and the sheet receiving tray portion, and the sheet convey portion and the sheet receiving tray portion can be shifted relative to each other in an arrangement direction of the sheet receiving tray means whenever the sheet is transferred. Further, there is provided detection means for detecting the fact that the sheet exists between the sheet convey portion and the sheet receiving tray portion.

Sheet sorter with sheet jam detection

An electrophotographic photosensitive member having a high sensitivity to long-wavelength light as emitted by a semiconductor laser and causing little change in potential change during repetitive use is formed by using as a charge-generating material a hydroxygallium phthalocyanine having a crystal form characterized by a strongest peak at a Bragg angle (2.theta..+-.0.2 deg.) of 28.1 deg. in a CuK.sub..alpha. characteristic X-ray diffraction pattern. The hydroxygallium phthalocyanine may preferably be produced through a process including treating a halogenated gallium phthalocyanine for conversion into a hydrous hydroxygallium phthalocyanine, freeze-drying the hydrous hydroxygallium phthalocyanine into a low-crystallinity hydroxygallium phthalocyanine, and milling the low-crystallinity hydroxygallium phthalocyanine.
