ABSTRACT:
An image forming apparatus sets operation modes different from an operation mode corresponding to a genuine article when the replaceable unit of the non-article article is mounted thereto, such that a user can select an operation mode via a UI device. And then, the image forming apparatus stores history information regarding an operation mode selected by the selection of the user, attribute information of a mounted replaceable unit (for example, a determination result of determining whether or not the replaceable unit is the genuine article), and history information (the number of printing sheets, error codes, or the like) of a printing process which is made in the operation mode, to be associated with each other.
