PURPOSE:To enhance the economization by providing a cylinder body provided with plural toner chambers independent of one another and distributing toners in toner chambers uniformly in the axial direction of the cylinder body to replenish toners without mixing the color. CONSTITUTION:Four toner chambers 1C, 1M, 1Y, and 1B independent of one another are formed in a cylinder body 1. For the toner chamber 1B, a rectangular toner replenishing hole 2B is formed in a part corresponding to the peripheral surface of the cylinder body 1 and in the rightmost part in the axial direction of the cylinder body, and a cover 3B is provided to open and close this toner replenishing hole 2B. A screw 7B as an agitating means which distributes the toner uniformly in the axial direction of the cylinder body is provided in the vicinity of a partitioning wall upstream in the rotational direction of the cylinder body 1. The turn direction of the screw 7B is reversed in a part corresponding to the toner replenishing hole 2B, and the toner replenished from the toner replenishing hole 2B is carried to both sides in the axial direction in accordance with the rotation of the screw and the toner is distributed uniformly in the toner chamber 1B. |
