摘要： An image forming apparatus (1, 1, 1") includes multiple image forming units (20Y, 20C, 20M) disposed adjacent to and horizontally aligned with each other, a first transfer member (15) to sequentially transfer and overlay respective single non-black color images thereon, a black image forming unit (20K, 20K', 20K") disposed separately from the multiple image forming units (20Y, 20C, 20M) including a black image carrier (2K) and a black image developing unit (4K, 4K'), a second transfer member (12) to transfer the black image from the black image forming unit (20K, 20K', 20K") onto a recording medium, a first cleaning unit (5K) to clean the black image carrier (2K), and a second cleaning unit (13) to clean the second transfer member (12). The black toner removed from the surface of the black image carrier (2K) is collected to the black image developing unit (4K, 4K').

摘要： A toner container for installation in a toner supply device is provided. The toner container includes a toner accommodation member and a cap member freely attachable to and detachable from the toner accommodation member. The toner accommodation member includes a bag member having an opening, and a connection member attached to the opening of the bag member and having a toner supply opening. The cap member is configured to receive toner supplied from the toner supply opening of the connection member of the toner accommodation member and to discharge the received toner. Either of the connection member of the toner accommodation member and the cap member includes a groove part and the other includes a protrusion part to engage with the groove part, and the cap member is attached to the toner accommodation member by engaging the groove part and the protrusion part with each other. The protrusion part elastically deforms to engage with the groove part.

摘要： A powder pump in a toner supply unit included in an electrophotographic image forming apparatus is driven by its exclusive motor independently of main motor provided for driving major parts of the image forming apparatus. The toner supply unit is therefore capable of implementing responsive supply of the toner unaffected by the operation mode change of the image forming apparatus with simpler construction of the supply unit. A toner supply system is also provided in a similar manner using plural power pumps for an image forming apparatus with a plurality color developing stations. By considering the distance and elevation of toner transport path to the respective stations, the appropriate number of pump revolution can be determined for respective stations. As a result, desirable amounts of toner transport to respective stations are suitably achieved in relatively short time with simpler construction of the supply unit. A method is also disclosed for implementing precise control of the amount of toner transport by the powder pump through suitable intermittent driving together with proper consideration of the characteristics of the powder pump. The powder pump is driven intermittently with an arbitrary unit driving time, and, when the arbitrary unit driving time is changed to another unit driving time, the pump is driven transiently with still another unit driving time different from the another unit driving time.
