Abstract: An image forming apparatus includes a printer unit; at least one of a copier unit and a facsimile unit; a lockable tray with a lock, to store a recording medium; an image formation controller to control at least one of the printer unit, the copier unit, and the facsimile unit in response to a request from a user. In response to a print request for printing using the lockable tray, the image formation controller determines whether the print request is from a user authorized to use the lockable tray based on association information between the lockable tray and the user authorized, and causes the printer unit to perform printing when the print request is from the user authorized. When the request is directed to the copier or facsimile unit, the image formation controller prohibits the copier or facsimile unit from performing printing using the lockable tray.

Abstract: An information processing apparatus includes an information storage to store information indicating a state of the information processing apparatus; an information writing processor to write the information to the information storage; a main power source and an auxiliary power source to supply power to the information writing processor; and a discharge controller to control a discharge speed of the auxiliary power source. When a voltage output of the main power source becomes a reference voltage, the discharge controller switches a power source for the information writing processor from the main power source to the auxiliary power source, and then after completing information writing to the information storage by using the information writing processor and the auxiliary power source, the discharge controller controls the discharge speed of the auxiliary power source to decrease a voltage output of the auxiliary power source to a given voltage within a given time period.

Abstract: An image forming apparatus includes a rotating member that is rotatable, a communication medium, and a receiving unit. The communication medium that is attached to an outer circumference of the rotating member stores therein information on the rotating member and relays the information on the rotating member via wireless communication. The receiving unit receives the information on the rotating member from the communication medium.
