摘要： An image forming apparatus includes an image forming unit configured to form an image on a sheet based on image data, a control unit configured to control driving of the image forming unit, and a power supply unit configured to, if a factor for shifting from a power saving state to a standby state is detected, supply power to the image forming unit and the control unit. If a first type of factor is detected as the factor in the power saving state, the power supply unit supplies power to the control unit and the image forming unit, and the control unit restricts the driving of the image forming unit. If an instruction to perform a function of forming an image on a sheet is accepted, the control unit cancels restriction of the driving of the image forming unit.

摘要： An image forming apparatus includes an image forming portion, an adjustment processing portion, an acquisition processing portion, and a setting processing portion. The image forming portion forms an image using toner. During execution of an image forming process using the image forming portion, the adjustment processing portion uses the toner to adjust the image quality of an output image output by the image forming process. The acquisition processing portion acquires variation amount information related to the amount of variation in a predetermined state value related to the image forming portion caused by a start of the image forming process. The setting processing portion sets the frequency of adjustment of the image quality of the output image by the adjustment processing portion, based on the variation amount information acquired by the acquisition processing portion.

摘要： A method for reducing artifacts in an electrophotographic printing system includes receiving a print job including image data for a set of pages. The electrophotographic printing system is used to print a block of pages from the print job to provide corresponding printed pages. The image data for the block of pages is analyzed to determine an average toner usage rate. If the determined average toner usage rate for the block of pages falls outside an acceptable toner usage rate range, image data for a compensation image and a number of compensation images are determined such that the average toner usage rate will be brought back into the acceptable toner usage rate range.

摘要： An image forming apparatus includes a plurality of print heads, a sensor, a processor, and an image forming unit. The plurality of print heads are arranged in parallel. The sensor detects a color shift amount of each color to be printed by the plurality of print heads in a main scanning direction based on an output result of a test pattern by the plurality of print heads. The processor sets a color shift correction value for correcting the color shift amount on the basis of a color having a largest color shift amount. The processor controls light emission of the plurality of print heads based on the color shift correction value and image data. The image forming unit forms an image based on the image data on a sheet by light emission of the plurality of print heads.

摘要： An image forming apparatus includes an image bearing member; a transfer member configured to transfer a toner image carried on the image bearing member to a sheet by being applied with a voltage; a controller configured to execute a mode of outputting a test chart for setting a voltage to be applied to the transfer member during image formation, the mode being a mode of transferring a plurality of test images to the test chart by applying a plurality of different voltages to the transfer member; and an operation portion capable of setting a type of a sheet on which the mode is executed. The controller is configured to preset a voltage value for setting a voltage to be applied when the test images are transferred in execution of the mode based on a voltage value, which is set in the previous execution of the mode.

摘要： An image forming apparatus includes a control unit configured to perform a first mode, a second mode, and a third mode. The first mode is a mode in which a sheet conveyance unit is controlled so that an arrival time from a passage of a trailing edge of a preceding sheet through a nip portion to an arrival of a leading edge of a succeeding sheet succeeding to the preceding sheet at the nip portion becomes a first time. The second mode is a mode in which the sheet conveyance unit is controlled so that the arrival time becomes a second time. The third mode is a mode in which the sheet conveyance unit is controlled so that the arrival time becomes a third time. The second time is longer than the first time, and The third time is longer than the second time.
