Abstract
An image forming apparatus saves, in a user database, a user ID used in user authentication processing and a department ID in association with each other, and saves, in a department database, the department ID and a number of sheets printed by a print unit in association with each other. The image forming apparatus performs deletion control to: in conjunction with accepting a deletion instruction for deleting the user ID and the department ID that are saved in the user database, delete the user ID and the department ID; and from out of department IDs saved in the department database, exclude a department ID not deleted from the user database by the deletion instruction to thereby execute processing to identify an unnecessary department ID, and delete the identified department ID from the department database.
