摘要： An image forming apparatus forms a plurality of tone patterns of different colors, each of which containing a plurality of toner patches having different toner densities. Some of the toner patches in each of the tone patterns are formed with a predetermined fixed developing bias and the rest of the toner patches in each of the tone patterns are formed with developing biases set based on previous developing biases that have been obtained through a previous control process. The largest toner density of the toner patches in each of the tone patterns is determined based on a magnitude relation of previous index values obtained through the previous control process.

摘要： In an image forming apparatus and an image density control method that are capable of suppressing the amount of toner consumed for a purpose other than image formation and responding to variation in the development ability of a development device due to environmental variation and the like such that a constant image density is obtained, the image density is maintained at a substantially fixed level by first target output value correcting means in accordance with a toner replacement amount and without consuming toner, and adjustment of the image density accompanying variation in the development ability due to environmental variation and the like is dealt with by second target output value correcting means in accordance with a toner pattern detection result. Hence, the frequency with which the toner pattern is detected in order to maintain the image density at a fixed level can be reduced in comparison with a case in which the image density is maintained at a fixed level on the basis of the toner pattern detection result alone, and as a result, the toner consumption amount can be suppressed.
