A post-processing apparatus of an embodiment discharges a sheet determined that writing of information to a wireless tag provided in the sheet is successful to a first paper discharge portion, and discharges a sheet determined that writing of information to a wireless tag provided in the sheet fails to a second paper discharge portion different from the first paper discharge portion.

A post-processing apparatus of an embodiment discharges a sheet determined that writing of information to a wireless tag provided in the sheet is successful to a first paper discharge portion, and discharges a sheet determined that writing of information to a wireless tag provided in the sheet fails to a second paper discharge portion different from the first paper discharge portion.

A sheet processing apparatus includes a processing unit, a sheet discharge unit, a determination unit, and a control unit. The processing unit performs crease processing on a sheet. The sheet discharge unit discharges a sheet having been subjected to the crease processing by the processing unit. The determination unit determines whether a number of the discharged sheets having been subjected to the crease processing exceeds a predetermined number of sheets. The control unit performs control to cause the discharge unit to discharge a sheet. In a case where the determination unit determines that the number of the discharged sheets having been subjected to the crease processing exceeds the predetermined number of sheets, the control unit performs control to cause the discharge unit to not discharge sheets having been subjected to the crease processing onto the discharge destination.

A paper humidifying apparatus includes humidifying rollers, a first drive unit and a controller. The humidifying rollers, forming a pair, are pressed against each other forming a nip portion and apply moisture to a sheet of paper when sandwiching and conveying the sheet of paper. The first drive unit which makes the humidifying rollers separate from each other or press against each other. The controller controls the first drive unit. The controller controls the first drive unit so as to make the humidifying rollers separate from each other and receive the sheet of paper, and after a tip of the sheet of paper passes a position corresponding to the nip portion, the controller controls the first drive unit so as to make the humidifying rollers press against each other to apply moisture to the sheet of paper.

An image forming system determines whether there is any recording material that is being conveyed in an image forming apparatus and that cannot be stopped at a predetermined position defined so as to avoid a location that causes a deformation of the recording material, when the conveying abnormality of the recording material is detected. Also, the image forming system determines whether there is any post processing apparatus in which the recording material can be stopped at an upstream side with respect to the post processing apparatus where the conveying abnormality occurs. Further, the image forming system discharges the recording material that cannot be stopped at the predetermined position in the image forming apparatus to a post processing apparatus at a downstream side with respect to the image forming apparatus and stops the recording material in the post processing apparatus.

An image formation system includes an image formation apparatus and a static elimination apparatus that performs static elimination of a sheet on which an image is formed by the image formation apparatus. The static elimination apparatus includes a conveyance unit that conveys the sheet, a static elimination unit that performs the static elimination of the sheet conveyed by the conveyance unit, and a signal transmission unit that transmits a certain signal based on a state of the static elimination unit. The image formation apparatus includes a signal reception unit that receives the signal transmitted by the signal transmission unit and a first notification unit that indicates content of notification corresponding to the signal received by the signal reception unit.

An image forming system includes an image forming unit including a first photosensitive member, a first developing unit, a second photosensitive member, a second developing unit, a third photosensitive member, a third developing unit, a fourth photosensitive member, and a fourth developing unit; a varnish applying unit; an irradiation unit; and a controller configured to control image formation by the image forming unit to form a black image, on which the varnish is superimposed, with yellow toner, magenta toner, and cyan toner.

An image forming system includes, an image former configured to form an image on a recording medium that is a flat cut sheet; a laminator that is disposed on a downstream side of the image former in a conveyance direction of the recording medium and that laminates the recording medium on which the image is formed by the image former; and a hardware processor configured to adjust at least one of a lamination speed in the laminator and/or an image forming speed in the image former.

A charge-eliminating apparatus includes a charge-eliminating member, a voltage applying unit, a setting unit for setting a value of a voltage applied to the charge-eliminating member by the voltage applying unit. A controller executes a changing process in which the value of a voltage to be output by the voltage applying unit is changed from the value of the voltage set by the setting unit during execution of a charge-eliminating operation in which the charge of a plurality of sheets is continuously eliminated by the charge-eliminating member. A selecting unit selects a first mode in which the changing process is performed during the execution of the charge-eliminating operation or a second mode in which the changing process is not performed during the execution of the charge-eliminating operation and the voltage is output by the voltage applying unit based on the value set by the setting unit.

An image forming device includes an image forming unit configured to form an image on a sheet, a fixing unit configured to fix the image on the sheet, the fixing unit including heating rotation body, a heater configured to heat the heating rotation body, and a pressure rotation body configured to form a nip portion between the heating rotation body and the pressure rotation body, a discharge roller disposed downstream of the fixing unit in a conveying direction of the sheet, and configured to discharge the sheet, a main motor configured to transmit a drive force to at least one of the heating rotation body or the pressure rotation body, a cutter disposed downstream of the fixing unit in the conveying direction, and configured to cut the sheet, and a controller.
