るトナー補給装置。(1) A toner replenishment device for an electrophotographic copying machine that has a replenishment roller at the lower end discharge port of a hopper-type toner tank, and replenishes toner in the developer consumed during development into the developer tank by rotating the replenishment roller. A stirring member that rotates in conjunction with the replenishment roller is provided directly above the replenishment roller at the lower part of the toner tank, and a cylindrical member having a diameter sufficient for the depth of the toner tank that allows the toner to pass through the outer peripheral surface is provided above the agitation member. A toner replenishing device further comprising a means for detecting a load on the stirring member, and a rotation of the cylindrical member is controlled based on a detection signal from the detecting means.
