Abstract
Disclosed is an image forming apparatus including: an image forming unit to form an image on paper fed from the selected feed tray; a density sensor to measure a density of the image formed on the paper; and a control unit to control execution of an output paper density adjustment in accordance with a result obtained by forming a test image on the paper by using the image forming unit and by measuring the density of the test image formed on the paper by using the density sensor, wherein the control unit executes the output paper density adjustment by changing the feed tray for feeding the paper, from the feed tray designated in a print job to the substitute feed tray at a predetermined timing while the print job is executed, regardless of the paper setting information related to the substitute feed tray.
