Abstract:
1. An image processing apparatus comprising: an image forming unit configured to form an image; an image control unit configured to control the image forming unit to perform a toner refresh operation that includes outputting deteriorated toner to form a first predetermined pattern having a predetermined density, and to control the image forming unit to form a second predetermined pattern; a sensor configured to measure a density value for each of the first and second predetermined patterns formed by the image forming unit; and a correction unit configured to correct a first toner density setting for a high-density operation of the image forming unit based on the measured density value of the first predetermined pattern formed during the toner refresh operation, and configured to correct a second toner density setting for at least a low-density operation of the image forming unit based on the measured density value of the second predetermined pattern, the low density operation requiring a lower toner density compared to the high density operation; the image control unit controlling the image forming unit to again form the second predetermined pattern after the first toner setting has been corrected by the correction unit, when the control of the toner refresh operation and the control of the formation of the second predetermined pattern are performed at the same time.
