摘要

An image-forming apparatus in which a replacement part is loaded includes a discrimination unit that discriminates whether or not identification data registered in the loaded replacement part correspond to either inherent data or group data registered in the image-forming apparatus; a determination unit that, when no correspondence is found in the discrimination unit, determines in accordance with a registration condition whether or not a value of the identification data is registered as the group data; and an establishment unit that establishes approval or disapproval of use of the loaded replacement part on the basis of a result of discrimination performed in the discrimination unit or determination performed in the determination unit.
