Abstract: A method of compensating for printing quality of an image forming apparatus includes determining a pattern to be printed as a first pattern which is a default pattern and a second pattern obtained by changing the first pattern according to a toner stress index that represents a deteriorated degree of remaining toner, and printing the determined pattern with the remaining toner.

Abstract: An image forming device capable of controlling an auto color registration (ACR) and a method of controlling an ACR. In the image forming device, a sensor detects preliminary test patterns by colors on a conveying belt; a color registration correction unit determines a present alignment state of the respective colors using data detected using colors by the sensor, and judges whether to perform a correction work of relative registration positions of the respective colors on the basis of the result of the determination; and a control unit forms actual test patterns on the conveying belt if it is judged that the correction work should be performed, and controls the sensor and the color registration correction unit to re-detect the data using colors and to perform the correction work.
