<P>PROBLEM TO BE SOLVED: To accurately control the amount of toner supplied from a toner storage container when a remaining toner reserving volume of a toner reserving section decrease, because the toner consumption amount is large in a state where an image of high printing rate must be printed continuously. <P>SOLUTION: The toner amount inside the toner reserving section can be kept at a predetermined amount by controlling the toner amount supplied from the toner storage container based on a signal of a toner amount detection sensor, so that packing is not caused in the toner reserving section, and reduction of the image concentration due to the lack of toner supply can be suppressed even in a state where the image of high printing rate is continuous. <P>COPYRIGHT: (C)2009,JPO&INPIT |
