FIELD: physics, computer engineering.
SUBSTANCE: invention relates to a function for re-execution of a task in an image forming apparatus, having a user authentication function. The image forming apparatus determines when a user authentication function is set as real, and a re-execution function for re-execution for re-execution of a task already executed is set as real, when re-execution function can be executed. The apparatus also determines when the user authentication function is set as invalid, when the re-execution function cannot be executed. The apparatus stores task information for an executed task when it is determined that the re-execution function can be executed. The apparatus allows an authenticated user to manipulate stored task information when it is determined that the re-execution function can be executed, user authentication is successful and the authenticated user is authorised to execute a task.
EFFECT: enabling control of storage of a processed task and manipulation of a stored task based on settings and user information in the apparatus.
