    摘要： A toner supply unit powder pump of an electrophotographic image forming apparatus is driven by an exclusive motor independently of a main motor driving major parts of the image forming apparatus. Thereby, the toner supply unit can implement responsive supply of toner unaffected by operation mode changes with a simpler construction. A toner supply system can use plural powder pumps for plural color developing stations. By considering distance and elevation of toner transport paths to respective stations, appropriate pump revolutions can be determined for respective stations, to achieve desirable toner transport amounts to respective stations in relatively short time with a simpler construction supply unit. A method precisely controls toner transport amounts by intermittently driving the powder pump with an arbitrary unit driving time. When the arbitrary unit driving time is changed to another unit driving time, the pump is driven transiently with the still another unit driving time.

    摘要： A developer replenishing device for replenishing a developing device with a developer, and a developer container for use therewith. The developer container, or toner bottle, has a mouth portion at one end thereof which is smaller in diameter than a hollow cylindrical main body. At the end of the bottle provided with the mouth, a shoulder has the inner periphery thereof partly raised to the edge of the mouth portion to form a raised portion for scooping up a toner. In addition, a part of the inner periphery of the circumferential wall of the bottle which is contiguous with the raised portion is also raised toward the axis of the bottle about which the bottle is rotatable, thereby forming another raised portion. When the bottle is mounted to a bottle holder, which is included in the replenishing device, substantially horizontally with the mouth portion oriented sideways, the bottle is rotated to raise the toner from the bottom of the main body to the mouth portion. As a result, the toner is discharged to the outside via the mouth portion smoothly.
