    Abstract: An image-forming apparatus includes an image formation section, a placement unit, a paper feed rotating body, a detecting body, a storage unit, and a determination unit. The detecting body detects the arrival of the paper having been supplied by the paper feed rotating body. The storage unit stores measurement data that is based on a measurement time from the start of paper feeding until when the detecting body detects the arrival. The determination unit finds the average time of the measurement times and, when the average time is longer than a predetermined theoretical time, establishes as the paper-non-feed jam detection time a time obtained by adding the absolute value of the time difference between the theoretical time and the average time to a detection reference time. The determination unit determines whether or not a paper-non-feed jam has occurred with the paper-non-feed jam detection time.

    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: An image forming apparatus of the present disclosure includes a plurality of image forming portions, an intermediate transfer unit, a secondary transfer member, a belt cleaning device, and a control portion. The intermediate transfer unit includes an intermediate transfer belt, a plurality of primary transfer members, a drive roller, a tension roller, and a contacting/separating mechanism. The belt cleaning device includes a cleaning member which faces the tension roller with the intermediate transfer belt therebetween. In a withdrawal mode, the cleaning member is moved by pressing force of the tension roller further into a housing from an opening portion as compared with in a printing mode. The control portion is capable of executing, while image formation is not being performed, a transfer toner collection mode in which the intermediate transfer belt and the belt cleaning device are driven in the withdrawal mode.

    Abstract: An image forming apparatus includes a pair of registration rollers, a pair of intermediate rollers, a registration sensor, and a control section that performs rotation control on the pair of registration rollers and the pair of intermediate rollers. The control section changes a starting timing of slowdown control according to a time when the registration sensor detects arrival of recording paper. The control section changes a period of time from completion of the slowdown control to start of increasing the rotational speed of the pair of registration rollers and the rotational speed of the pair of intermediate rollers from a lower speed limit to a steady state speed according to the change of the starting timing of the slowdown control.
