A sheet conveying apparatus of an embodiment includes a conveyance path along which a sheet can be conveyed, and a plurality of conveyance rollers configured to move a sheet along the conveyance path. A wireless tag reader/writer is configured to read information from, and write information to, a wireless tag of a sheet on the conveyance path. A phase change detector is configured to detect a phase change in response waves received by the wireless tag reader/writer from a wireless tag. A tag specifying unit is configured to identify whether a wireless tag is moving along the conveyance path based on the detected phase change in response waves from the wireless tag. A controller controls the wireless tag reader/writer to write information to the wireless tag identified as moving along the conveyance path.

A static elimination device includes: a first static elimination member that makes contact with a medium that is transported; a second static elimination member arranged such that the medium is inserted between the first static elimination member and the second static elimination member; and a power source that applies a voltage to at least one of the first static elimination member or the second static elimination member, in which at least one of the first static elimination member and the second static elimination member has an elastic body.

A paper guide member includes plural thread-shaped protrusions extending in a passing direction of paper to guide the paper after a toner image is transferred so that the paper passes with a distance secured from a static eliminator that eliminates static electricity in proximity to the paper in a width direction of the paper. The plural thread-shaped protrusions adjoin each other across a slit in the width direction of the paper. The plural thread-shaped protrusions include first thread-shaped protrusions each having a height at which the paper is supported and guided, and second thread-shaped protrusions each having a height smaller than the height of each of the first thread-shaped protrusions and present in regions on an outer side of both ends in the width direction of each passing region where paper having each width passes.

A feeding apparatus includes a feeding unit, an ion generating unit and a controller. The ion generating unit irradiates the sheet fed by the feeding unit with the ion. The controller acquires an information on the fed sheet and to controls the ion generating unit. The controller operates the ion generating unit in a case that the information of the sheet is a first information, and does not operate the ion generating unit in a case that the information of the sheet is a second information.

A sheet conveying apparatus of an embodiment includes a conveyance path along which a sheet can be conveyed, and a plurality of conveyance rollers configured to move a sheet along the conveyance path. A wireless tag reader/writer is configured to read information from, and write information to, a wireless tag of a sheet on the conveyance path. A controller is configured to detect a phase change in response waves received by the wireless tag reader/writer from a wireless tag. The controller is also configured to identify whether a wireless tag is moving along the conveyance path based on the detected phase change in response waves from the wireless tag. The controller controls the wireless tag reader/writer to write information to the wireless tag identified as moving along the conveyance path.

The image forming system having an image forming apparatus and a charge adjusting apparatus has a decision unit that decides an amount of charge to be applied to a recording sheet from coverages of toner images of both surfaces of the recording sheet, the image forming apparatus has a fixing unit that heats and presses a recording sheet to which a toner image is transferred, thereby fixing the toner image to the recording sheet, and the charge adjusting apparatus has a voltage applying unit that applies a voltage to the recording sheet to which the toner image is fixed by the fixing unit, thereby applying charge with the amount decided by the decision unit to the recording sheet.

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.

It is difficult for a user to select an appropriate maintenance method for a non-contact charge removal unit. A charge removal apparatus includes a non-contact charge removal unit including an electrode portion for generating ions and configured to remove charge of a sheet using the ions generated by the electrode portion in a non-contact state with the sheet on which an image is formed by an image forming unit, and a display unit configured to selectively display a cleaning method of the electrode portion from among a plurality of cleaning methods.
