Abstract:
1. An image forming apparatus including: an image processing unit that performs image processing of an image signal using an image processing condition; an image forming unit that forms an electrostatic latent image on a photosensitive member, based on the image signal processed by said image processing unit; a developing unit that develops the electrostatic latent image using a toner; a decision unit that decides a toner supply amount, wherein the toner supply amount is an amount of the toner to be supplied to said developing unit; a prediction unit that predicts a toner consumption amount based on the image signal; an acquisition unit that acquires a time of toner agitation by said developing unit; an estimation unit that estimates a toner charge amount in said developing unit based on the toner consumption amount predicted by said prediction unit, the toner supply amount decided by said decision unit, and the time of toner agitation acquired by said acquisition unit; and a correction unit that corrects a tone characteristic of the electrostatic latent image to be developed by said developing unit based on the toner charge amount estimated by said estimation unit.
