Abstract
For each of N imaginary regions divided at predetermined intervals in the direction of the rotation shaft of a developer roller (12), the amount of toner consumed when an image is formed is previously calculated. Then, the same amount of toner as a toner consumption amount calculated for each imaginary region is supplied to a development device (2) earlier by a time in which the toner supplied from a toner hopper (5) is transported to each imaginary region than at the time of the development. Thus, it is possible to maintain a toner concentration within the development device within a predetermined range without the toner being dispersed and an image formation speed being reduced even if an image having a high print rate is formed.
