A post-processing apparatus includes a folding section configured to nip a sheet using a plurality of rollers to form a fold line for saddle stitching and a control section to control the nipping amount in the folding section. When carrying out square back processing to flatten the spine folded portion of a sheet bundle where a fold line for saddle stitching is formed, the post-processing apparatus allows the nipping amount in the folding section to be smaller than that in the case where the square back processing is not carried out.

Square back processing with variable nipping

A notch forming device, comprises a notch forming section to form a notch on an edge of a sheet constituting a sheet bundle to be outputted in accordance with an execution of a job; a shifting section to shift a position of a notch to be formed on a sheet by the notch forming section; and a control section to control the shifting section. When plural sheet bundles are outputted in accordance with the execution of the job, the control section controls the shifting section to make a position of a notch on a leading sheet of each sheet bundle at the same position.

Notch forming device, bookbinding apparatus and bookbinding system

A sheet post-processing apparatus including: an open-close door; a stapler which executes a staple processing to a bundle of sheets; a staple jam detection section which detects a staple jam; a stapler moving section which moves the stapler to an access position disposed close to the open-close door; a stacker which holds the bundle of sheets to be stapled; a sheet sensor which detects whether a sheet exist on the stacker; and a controller which controls the stapler moving section, wherein when the staple jam detection section detects a staple jam, the controller controls to operate the stapler moving section to move the stapler from a home position to the access position, and wherein, when the sheet sensor detects the sheet on the stacker, the controller prohibits to move the stapler to the access position.

Sheet post-processing apparatus and image forming system

A sheet holding apparatus having: a feeding mechanism to feed a sheet on which an image is formed by an image forming apparatus, from a predetermined feeding position; a tray section having a tray to contain the sheet fed through the feeding mechanism; an initialization mechanism to initialize the tray section; and a control section to make a determination about necessity or unnecessity of an initialization of the tray section and/or a content of the initialization on the basis of information about a position of the tray, which is notified from the image forming apparatus, and to control the initialization of the tray section through the initialization mechanism according to the determination.

Sheet holding apparatus and image forming system

The present invention concerns a fixing apparatus and an image-forming apparatus. The fixing apparatus and the image-forming apparatus include a heating roller; a heating element disposed in the heating roller; a pressing roller pressure-contacting the heating roller to fix an image onto a transfer sheet passing through a pressure-contacting section between the heating roller and the pressing roller; and a cooling device to cool the heating roller. In the fixing apparatus, the cooling device is activated during a predetermined time period after consecutive fixing operations are completed. While, the image-forming apparatus further includes a control section to activate the cooling device during a predetermined time period after consecutive fixing operations are completed.

Fixing apparatus and image-forming apparatus

There is described an image forming apparatus favorably applied to a copying machine equipped with a control function for jobs including image forming processing. The image forming apparatus includes an image forming section to form an image, a sheet-feeding/conveyance section to convey a recording sheet, a controlling section to control the image forming section and the sheet-feeding/conveyance section and a memorizing section to memorize jobs reserved for an image forming processing. The image forming processing for one of the jobs includes a startup operation, an image forming operation and a terminating operation. When the memorizing section memorizes a next job to be executed next to a current job, which is currently executed in the image forming apparatus, the controlling section controls the image forming processing so as to perform the image forming operation for the next job succeeding to that for the current job, without performing the terminating operation for the current job and the startup operation for the next job.

Image forming apparatus having controller which controls jobs including image forming processing and which executes jobs in succession

An automatic two-sided recording apparatus having an image forming station to form an image on a recording sheet and a sheet feeder to feed the recording sheets onto the station, includes an intermediate stacker having an inlet through which a recording sheet whose one side has been subjected to recording is stacked thereon by a switchback member provided adjacent to the inlet. The inlet is used also an outlet through which the recording sheet is fed out for recording on the other side thereof by the switchback member through a conveyor. The apparatus further includes a controller that switches between a stackless mode in which the switchback member feeds in the recording sheets the stacker and feeds out onto the station without stacking in the stacker, and a stack mode in which the switchback member feeds in and feeds out from the stacker onto the station after stacking in the stacker. The apparatus further includes a measuring member to measure one copy cycle time in the course of an image forming on one side. The controller determines the number of recording sheets to be handled in the stackless mode and that of recording sheets to be handled in the stack mode, based on the copy cycle time measured and a preset copy quantity, and switches the modes in accordance with the determined number of sheets.

Two-sided recording apparatus

An electrophotographic copying machine capable of inserting an inter-sheet in a copy of a document. A width-detector is provided to detect the width of an inter-sheet contained in an inter-sheet tray. A judging circuit determines if the detected width of the inter-sheet is within an allowable width range. If the detected width is not within the allowable width range, the inter-sheet is inhibited from being fed and reminder information is displayed. If the inter-sheet is required to be blank with no image of the original recorded thereon, an automatic document feeder is controlled so as to stop feeding the original sheet while the inter-sheet is conveyed to be placed at the insert-page. The adjustment of copy image density, including scanning of the original sheet, is also stopped.

Copier with automatic insert feed having an interrupt function

The invention provides a copying apparatus for producing a required number of copy sets of two-sided copy from document sheets of an original by selecting one of ADF mode in which the required number of copy sets are produced simultaneously and RDH mode in which the required number of copy sets are produced one set by one set.
