Patent ID: 7619791

Claim:
An image forming method for forming an image using an image forming apparatus comprising: a developing unit for containing a two-component developer including toner and carrier; a toner density detecting unit for detecting a toner density in the developing unit; a humidity detecting unit for detecting humidity information around the developing unit; a toner supply unit for supplying toner to the developing means; a toner supply control unit for controlling the toner supply unit by comparing an output value from the toner density detecting unit with a toner density reference value stored in memory unit; and an image density correction control unit for forming a reference developing image based on a set value of a predetermined image forming condition, detecting a density of the formed reference developing image, and correcting the set value, the method by comprising: a determination step for determining whether or not a set value of an image forming condition has been corrected beyond a predetermined range with respect to an initial value; a humidity detection step for detecting humidity by the humidity detecting unit when a determination is made in the determination step that a correction value with respect to the initial value exceeds the predetermined range; a correction value determination step for determining a correction value of the toner density reference value, based on the humidity detected in the humidity detection step; and a step of correcting the toner density reference value using the correction value of the toner density reference value determined in the correction value determination step.
