Patent number: 7003233Abstract: There is provided an image forming apparatus including the first developing agent storing section which stores toner, a toner replenishing member for supplying the toner in the first developing agent storing section to the second developing agent storing section, and a controller which controls operation of the toner replenishing member on the basis of information about the amount of toner used in the first developing agent storing section and information about the fluidity of the toner. By more accurately controlling a toner discharge amount of a toner replenishing container and detecting the remaining toner, the toner density in a developing unit can always be kept constant to meet the demand for higher-quality images. There can be provided an inexpensive compact image forming apparatus in which the replacement timing of a developing agent replenishing container is delayed to obtain a longer service life.Type: GrantFiled: August 27, 2003Date of Patent: February 21, 2006Assignee: Canon Kabushiki KaishaInventors: Kenji Matsuda, Hisayoshi Kojima, Akiyoshi Fujita
