Abstract: In an image forming apparatus, in a case of duplex printing, a sheet is transported toward an image forming device along a sheet transport route, the image forming device forms an image on a first face, which is one of faces of the sheet, a reverse transport device reverses the front and back faces of the sheet and transports the sheet to a position upstream of a show-through reading device in a sheet transport direction, and the show-through reading device reads a second face, which is another face of the sheet. Then the show-through detector decides whether a show-through has occurred, on a basis of the image that has been read.

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 formation system includes an image forming apparatus and an inserter. The image forming apparatus includes an image forming device, a conveyance device, and a control device. The control device functions as a controller and an executor. The controller allows the inserter to insert an interleaving paper between sheets of printed material at an insertion start timing specified by a print job. When the plurality of calibrations include a second calibration capable of being completed within an interleaving paper insertion time required to insert the interleaving paper or a third calibration capable of being completed within a total time of the interleaving paper insertion time and a predetermined additional time, the executor executes the second calibration or the third calibration in time with the insertion start timing.

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 system includes an image forming apparatus and an insertion device. The image forming apparatus includes an image forming device, a transport device, and a control device. The control device acts as a controller and an executer. The controller causes the image forming device to execute a printing job, and causes the insertion device to insert the interleaving paper in a printed material at an insertion start timing designated by the printing job. The executer executes calibration at an execution start timing set in advance, and sets a time point that a predetermined time has elapsed after a previous calibration to the execution start timing in advance. The executer starts to execute the calibration at the insertion start timing, when a predetermined condition is satisfied.

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.
