PURPOSE:To eliminate the uneven distribution of toners in a toner box, by juxtaposing a plate-like body erected with plural projections assuming a polygonal shape together with a dispenser roll in a toner box, and moving the plate-like body back and forth. CONSTITUTION:A dispenser roll 10 is turnd by a motor M, and the toners T in a toner box 1 are supplied into an agitating tank for the developer; at the same time, a cam 8 is also rotated by gears 6, 7, and a grid plate 20 is moved back and forth in the revolving axis direction of the roll 1 by the revolution of the cam coupled with the effect of a compression coil spring 22a. As the plate 20 moves back and forth, the toners T are moved respectively in different directions by the effect of rhombic projections 21a-21d. As a result, the toners T are distributed uniformly in the box 1. The toners in the agitating tank for the developer are thus distributed uniformly, and the density differences on copies are eliminated. |
