Patent ID: 7978995

Claim:
An image forming apparatus which performs at least a correction processing of color misregistration in an image formation system and a correction processing comprising an image density adjustment, the image forming apparatus having a process correction mode wherein when a temperature of a fixing device in the image formation system in a power-on state is equal to or less than a predetermined value, the image forming apparatus being configured to increase a temperature of the fixing device to the predetermined value, such that the image density adjustment can be performed, the image forming apparatus comprising: (a) a first detector which detects presence of the power-on state for the apparatus; (b) a second detector which detects a fixing temperature in the fixing device; and (c) a controller which sets the process correction mode based on power-on information output from the first detector and fixing temperature information output from the second detector, and sets a priority level for performing the correction processing of the color misregistration to be lower than the correction processing of the image density adjustment.
