ABSTRACT:
An image forming method and an image forming apparatus whereby the density of a toner image of a reference pattern hvaing a predetermined density is measured, based on which image forming conditions are controlled. The image forming conditions is at least one of the quantity of exposure light given to a document, the charging amount with which a photosensitive body is charged and the voltage applied to a developing device. The toner image is formed only at an optional point set in a direction of a rotary shaft of the photosensitive body for measuring the density. Therefore, a waste of toners can be prevented. Moreover, since the density of the toner image formed at the optional point in the direction of the rotary shaft of the photosensitive body is measured, correction of the density can be carried out at the optional point.
