Toner of which the charge amount is reduced by leaving the toner till reception of a next image forming processing instruction after the end of preceding image forming processing is charged by the development sleeve 4a and the developer supply roll 4b if necessary, and thus an image having a stable density is obtained without unnecessary toner consumption. |
