Abstract

An image forming apparatus includes: a hard disc drive storing a database including image formation authority of a registered user and a remaining available amount and ID information for specifying the remaining available amount of the database to be updated based on processing detail data serving as data indicating processing details of the image forming apparatus; an image forming device; an auxiliary storage device storing processing management data including the processing detail data; and a controller managing details of processing performed by the image forming device. After ending of processing performed by the registered user, the controller uses the processing management data stored in the auxiliary storage device to update the remaining available amount specified by use of the ID information and deletes the processing management data from the auxiliary storage device in response to completion of the update.
