Abstract
This invention is to provide a technique of always obtaining a stable output image in image formation using toner. A supplier (1217) supplies toner in a decided toner supply amount. A developing device (1206) agitates the supplied toner and supplies the agitated toner to an electrostatic latent image formed on a photosensitive drum (1203), thereby developing a toner image on the photosensitive drum (1203). A correction amount calculation unit (1106) estimates the toner charge amount by calculating a function model that approximates the variation characteristic of the toner charge amount using the toner consumption necessary for printing a print target image, the toner supply amount necessary for printing the print target image, and the toner agitation time. At least one of an image processing condition and a process condition is controlled using the estimated toner charge amount.
