An image forming apparatus includes: image former forming an image on a sheet; a sheet storage storing the sheet; a sheet feeder feeding the sheet stored in the sheet storage to the image former; a sheet characteristic detector detecting characteristics of the sheet fed by the sheet feeder; and a hardware processor controlling image forming in the image former on the basis of the sheet characteristics detected by the sheet characteristic detector, wherein the sheet feeder feeds a first sheet in order to detect the sheet characteristics by the sheet characteristic detector before forming an image by the image former, and after the sheet characteristic detector has finished detecting the characteristics of the first sheet, the sheet feeder feeds a second sheet on which the image is to be formed by the image former under image forming conditions set on the basis of the detected characteristics of the first sheet.

Image forming apparatus and image forming method

An image forming apparatus includes: sheet feed trays on which sheets are placed; a transferrer that transfers an image formed by an image forming part onto a sheet at a transfer position; conveyance roller pairs provided along conveyance paths from the sheet feed trays to the transfer position and that conveys a fed sheet; a conveyance position detector that detects a conveyance position of a conveyed sheet in a width direction; a sheet position adjuster that performs adjustment of the conveyance position of the sheet in the width direction by using an amount of displacement; and a hardware processor that determines, on the basis of a sheet feed tray that is to be used among the sheet feed trays and a sheet length of a sheet that is to be fed from the sheet feed tray, whether or not the adjustment of the conveyance position is to be performed.

Image forming apparatus and method for controlling image forming apparatus

An image forming apparatus of the present invention includes: an image forming unit for forming an image on a continuous paper; a fixing unit for fixing by heat the image which has been formed on the continuous paper by the image forming unit; conveyance units for conveying the continuous paper; and a control unit for controlling the conveyance units to convey the continuous paper in such a manner that, when an image forming operation by the image forming unit is stopped, the same portion of the continuous paper, on which the image is not formed, does not remain in the fixing unit for a predetermined period of time.

Image forming apparatus that controls movement of a continuous sheet through a fixing unit

In an image forming system equipped with a small-sized post-processing apparatus capable of producing pamphlets without being limited in terms of the number of sets, a folding device, an interposing device and an ejecting device for ejecting a pamphlet formed by interposing a sheet into a sheet to be folded are provided in the post-processing apparatus.

Image forming system and pamphlet producing method

An image forming system including a binding system section that generates a stack of sheets by accumulating a plurality of sheets and that binds the sheets by wrapping the stack of sheets with a cover sheet in the shape of a horizontal U, the image forming system having: a measurement section to measure the thickness of the stack of sheets; a spine cover width determining section to determine a spine cover width in the cover sheet based on the thickness of the stack of sheets measured by the measurement section; and an image forming section to form on the cover sheet a front cover image and a back cover image separating them by a spacing equal to the spine cover width.

Image forming system

An image forming apparatus comprises: an image reading section for reading a plurality of document images of a document having a plurality of sheets page by page, the document being set on a reading position in a state that image directions of the document images are mixed; a designating section for designating each image direction of the document images of the document set on the reading position; a storing section for storing the document images read by the image reading section; an image forming section for recognizing each rotation angle for directing the stored document images to a reference direction which is previously set, in accordance with each designated image direction, and for forming a plurality of output images by rotating the document images by each recognized rotation angle; and an output section for outputting the formed output images.

A sheet finisher includes: a sheet stacker for stacking sheets outputted from an image forming apparatus to form a sheet bundle; a binder for binding the sheet bundle stacked on the sheet stacker; an ejection device for ejecting out of the sheet finisher at least one of the sheet bundle stacked on the sheet stacker and the sheet bundle which has been bound; an ejection tray for stacking the ejected sheet bundle or the bound sheet bundle sequentially; and a controller for controlling the ejection device to make the bound sheet bundle to wait on the sheet stacker, to make a sheet outputted from the apparatus which have not been bound to stack sequentially on the bound sheet bundle, and to make the bound sheet bundle and the sheet stacked on the bound sheet bundle as a unit to eject to the ejection tray.
