Abstract: A cleaning member (16) for cleaning an open/close mechanism (14) for opening/closing a supply port (1a) of a toner cartridge (1) is moved in sync with operation of the open/close mechanism. The cleaning member (16) is in contact with the open/close mechanism (14) for scraping the toner from the outside surface of the open/close mechanism (14), thus preventing the toner from dirtying the unit, etc. when the toner cartridge (1) is removed.

Abstract: A contact pressure setting method of setting a contact pressure between contact members of an image forming apparatus. A film member is inserted into a gap between the contact members and the contact pressure is set so that a pulling force to pull out the film member lies within a predetermined range. Thus, the contact pressure can be accurately and easily recognized and the contact pressure can be set to be uniform.

Abstract: A toner container (101) is detachably attached to a developing device (104). A toner (120) stored in the toner container (101) is supplied through a supply opening (104a) to a hopper (105) of the developing device (104). A movable shutter (123) is provided below the supply opening (104a). The shutter (123) opens the supply opening (104a) when the amount of the toner (121) in the hopper (105) is less than a predetermined amount, and closes the supply opening (104a) when the amount of the toner (121) in the hopper (105) is greater than or equals to the predetermined amount.

Abstract: A toner container 40 includes a fresh toner chamber 46 and a waste toner chamber 47 separated by a partition wall 45. A width “a” of the interior of the fresh toner chamber 46 at an arbitrary vertical position VP along the partition wall 45 is substantially equal to or less than a corresponding width “b” at another position below the vertical position VP. The waste toner chamber 47 has a waste toner collection opening 55 through which a toner discharging mechanism 32 is inserted. A guide member 56 guides a discharging lid 57 for opening and closing the waste toner collection opening 55. The guide member 56 extends inwardly from the vicinity of an upper periphery of the waste toner collection opening 55, so that the toner discharging mechanism 32 that has entered in the waste toner chamber 47 is covered by the guide member 56 from above.

Abstract: An image-forming apparatus includes a mechanism that controls the replenishment amount of toner to a predetermined value. A toner cartridge holds toner therein. The toner cartridge is detachably attached to a process cartridge. The process cartridge has a toner reservoir that holds the toner supplied from the toner cartridge, a photoconductive drum and a developing roller that supplies the toner to the photoconductive drum. A valve is located between the toner cartridge and the process cartridge and supplies the toner from the toner cartridge to the process cartridge. When the valve rotates, the valve supplies a volume of toner in such a way that the toner in the toner reservoir fills a volume not more than a predetermined fraction of a maximum capacity of the toner reservoir.
