An image forming apparatus includes a plurality of cassettes which store paper sheets of different sizes and a feeding device for feeding the paper sheets one by one. The image forming apparatus forms an image on the paper sheet fed by the feeding device. A size detector detects the size of the paper sheet which is used. A copying fee is calculated based on the size and number of the sheets used.
