ABSTRACT:
An image forming apparatus includes a paper storage part; weight sensors for measuring the weight of paper stored in the paper storage part; a paper feed counting part for counting the number of sheets fed from the paper storage part; a memory unit for storing the weight A applied to the weight sensors, exclusive of the weight of paper, the weight B of standard paper, and the set number C of sheets for checking that specifies the intervals at which the remaining quantity of paper is to be checked; a control panel; and a CPU. The CPU accurately calculates the actual weight of each sheet of paper from a change in paper weight per feed of the set number C of sheets for checking.
