Abstract
An image forming apparatus includes an image creation device loaded in the image forming apparatus in a replaceable manner, an openable and closable cover to be opened and closed when the image creation device is to be replaced with a new one, a new/old discrimination portion that discriminates whether the image creation device is new or old, an image stabilization processing portion that executes image stabilization processing for old image creation devices to maintain image quality with respect to old image creation devices and executes image stabilization processing for brand-new image creation devices including a part of the image stabilization processing for old image creation devices as common-processing to maintain image quality with respect to brand-new image creation devices, and a controller. The controller makes the new/old discrimination portion initiate new/old discrimination processing at the time of turning on power supply and/or closing the openable and closable cover, makes the image stabilization processing initiate common-processing common to image stabilization processing for old image creation devices and that for brand-new image creation devices, and makes the image stabilization processing initiate image stabilization processing peculiar to brand-new image creation devices or old image creation devices depending on a discrimination result of the new/old discrimination portion after completion of the common-processing.
