Abstract: An image forming apparatus connected to a charging device includes an image forming unit, a fixing unit, a charge processor, a controller, and a printed sheet counter. The charge processor charges a fee for printing. The controller selects an energy saving mode, upon deciding that a balance of a deposited amount in the charging device is less than a threshold amount. The printed sheet counter counts the number of sheets of the recording medium printed by the image forming unit in one single printing job. The controller selects the energy saving mode for the next printing job, upon deciding that the number of sheets printed in one single printing job is less than a predetermined threshold number of sheets, when the deposit balance is remaining in the charging device.

Abstract: A continuous reading mode is a mode in which reading of a document placed on a contact glass is continued and a job is started after completion of reading is accepted. In reading of the second and subsequent sheets of the document in a set reading range, a reading controller does not move the position of the reading line of an image sensor to outside the end position of the reading range in the sub-scanning direction as seen from a home position.
