Abstract: An image forming apparatus includes an image forming portion, an exposure device, an image density sensor, and a control portion. The control portion can, by adjusting the development voltage based on the image density of a reference image and the amount of exposure from the exposure device, perform image density correction to adjust the image density. The control portion predicts the toner charge amount based on a formation condition of the reference image and the image density of the reference image and determines the timing of performing the image density correction next time based on the rate of change of the toner charge amount calculated using a first toner charge amount predicted when the image density correction was performed last time, a second toner charge amount predicted when the image density correction is performed this time, and the interval between the image density correction performed last time and this time.

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 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.
