ABSTRACT:
An image forming apparatus has a unit in which at least an expendable component is incorporated. The unit is reusable by periodically replacing the expendable component. An indicator for indicating a record on use of the unit is attached to a given position on the unit. The record on use can be associated, for example, with one or more of the number of times of re-using the unit, a period lapsed from start of use of the unit, and the total number of times of using the unit with respect to image formation.
