An image forming apparatus includes a main body that includes a photosensitive member on which an electrostatic latent image is formed and a development unit configured to develop the photosensitive member with toner. The main body is configured to discharge a recording material on which an image is formed with the toner onto a discharge tray. The image forming apparatus also includes a toner supply port on which a supply container is mounted to supply toner to a toner containing portion of the development unit. The image forming apparatus further includes a non-contact communication portion including an antenna and configured to receive a signal for user authentication. The discharge tray, the toner supply port, and the non-contact communication portion are provided at an upper portion of the main body. The non-contact communication portion is provided outside the discharge tray when the main body is viewed from above.

A cartridge including a carrier storing an authenticity verification code readable by a scan device other than a host device and an auto-destruct feature to render the authenticity verification code unreadable at installation.

An image forming apparatus includes: an image forming unit; a housing configured to store the image forming unit, the housing including an outer peripheral wall; a power supply unit disposed inside the housing; and a near field communication board including an antenna for near field communication, the near field communication board being disposed at a position of the outer peripheral wall apart from the power supply unit by a communicable distance or more.

Disclosed is an image forming apparatus that includes: a detecting unit configured to detect a user approaching the image forming apparatus; a communication unit configured to be capable of receiving the job from a mobile terminal via short-range wireless communication; and a controlling unit that controls a power supply such that electric power is supplied from the power supply to a first device and a second device in response to detection of the user by the detecting unit, and controls the power supply such that in response to designation of a job from the mobile terminal via the short-range wireless communication, the power supply continues supply of the electric power to the first device that is used for executing the designated job and the power supply stops supply of the electric power to the second device that is not used for executing the designated job.

According to one embodiment, an image forming apparatus includes a reading unit, a heating unit, and an updating unit. The reading unit reads area designation information for designating an area to be decolored in areas of a sheet on which an image that can be decolored by heating is formed and history information for indicating the number of times of performing decoloration in the past for each area of the sheet from a wireless tag attached to the sheet. The heating unit heats the area based on the area designation information read by the reading unit. The updating unit updates the history information stored in the wireless tag which corresponds to the area heated by the heating unit.

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 discharge tray, the toner supply port, and the non-contact communication portion are provided at an upper portion of the main body. The non-contact communication portion is provided outside the discharge tray when the main body is viewed from above.

An image forming apparatus connected to a user terminal includes: an apparatus side connecting part; a connection detecting part; an apparatus side mode switching part; and an apparatus side mode setting part. The apparatus side connecting part connects to the user terminal and outputs connection information. The connection detecting part detects whether or not the apparatus side connecting part is connected to the user terminal based on the connection information and outputs detection information. The apparatus side mode switching part outputs, based on the detection information, mode information indicating a mode to which a consumption amount of a resource consumed by the image forming apparatus is allocated. The apparatus side mode setting part sets, based on the mode information, an energy saving mode in which the consumption amount is reduced as compared with the consumption amount when the apparatus side connecting part and the user terminal are connected.
