Abstract
A chip mountable on a replaceable unit used in an image forming job is disclosed. The chip includes a central processing unit (CPU) to perform at least one of authentication and cryptographic data communication with a main body of the image forming apparatus using an operating system (OS) of the CPU which operates separately from an OS of the image forming apparatus. With the use of such a configuration, security for a unit in which the chip is mounted can thereby be reinforced.
