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.

Image forming apparatus the controls operation depending on whether show-through of sheet is detected

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.

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.

An image forming apparatus includes a control portion, a stop processing portion, a resumption processing portion, and a notification processing portion. The control portion, to which power supply is stopped when an operation mode of the image forming apparatus is a power-saving mode, measures an elapsed time until when printed matter processed according to the print job is collected. The stop processing portion, when the operation mode shifts to the power-saving mode, stops measurement of the elapsed time before power supply to the control portion is stopped. The resumption processing portion, if the printed matter exists in the sheet discharge portion when the operation mode shifts to a normal mode, resumes measurement of the elapsed time by the control portion. The notification processing portion, when the time measured by the control portion reaches a predetermined first reference time, notifies that the printed matter has not been collected.

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.

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.

An image forming apparatus includes a discharge tray; a printing unit; a stacking controlling unit that determines a front side value related to toner amount on a front side of a sheet and a back side value related to toner amount on a back side, determines an absolute value of difference between the front side value and the back side value for each sheet, determines a correction value of each sheet based on the absolute value and correction value data, adds the correction value to a predetermined value for determining a corrected count value of each sheet, integrates the corrected count value, and detects full of the discharge tray when the integrated value reaches a predetermined upper limit value; and a storage unit for storing the correction value data in which the correction value is determined corresponding to the absolute value.

Image forming apparatus and method for controlling image forming apparatus

An image forming apparatus includes: a transfer unit, a reflectance sensor, a time-series data acquiring unit, and a transfer-unit rotation-time calculating unit. The time-series data acquiring unit is configured to acquire time-series data with respect to the image carrier background-portion reflectance, measured by the reflectance sensor, as reference data over a time period twice longer than a time period that by design the image carrier requires for one cycle, and as advance/delay data over a time period twice longer than a time period longer or shorter in multiples of a predetermined time interval than the by-design time period. The transfer-unit rotation-time calculating unit is configured to calculate a one-cycle-time calculation value that is the time actually required for one cycle of the image carrier, based on the reference data and the advance/delay data acquired by the time-series data acquiring unit.
