Abstract
An image forming apparatus comprises an inner memory, first checking means, second checking means, a mode selector, judging means and a portable memory. The portable memory is adapted to be connected to the main body of the apparatus and memorizes a portable memory identification number to identify the same portable memory and a plurality of usable apparatus numbers to represent usable image forming apparatuses which become usable by the connection of the same portable memory. The inner memory memorizes an apparatus identification number to identify the image forming apparatus and a plurality of acceptable portable memory numbers to represent portable memories acceptable for the same image forming apparatus. The first checking means checks if the apparatus identification number coincides with any of the usable apparatus numbers, and the second checking means checks if, the portable identification number coincides with any of the acceptable portable memory numbers. The mode selector selects a check mode which determines a combination of checks to be performed by the first and the second checking means, and the judging means allows usage of the image forming apparatus based on the result of the combined checks.
