Abstract:
1. An image forming apparatus for developing, on a recording medium, an image corresponding to image data, by use of two-component developer constituted of toner and carrier, said image forming apparatus comprising: a developing chamber for containing the two-component developer used for development of the image; a supply member for supplying toner to the developing chamber; a toner consumption amount calculation section for calculating, based on the image data, an amount of toner consumption accompanying the development of the image corresponding to the image data; a corrected consumption amount calculation section for calculating a corrected consumption amount by multiplying the calculated amount of toner consumption by a predetermined correction ratio that is less than 1, so that the corrected consumption amount is always smaller than the actual toner consumption; and a toner density control section for causing the supply member to perform main supply in which toner is supplied to the developing chamber based on the calculated corrected consumption amount and for controlling toner density of the two-component developer contained in the developing chamber.
