Abstract
A developing device incorporated in image forming equipment and having a toner tank made up of a tank portion and a toner supply portion contiguous with one side of the tank portion for supplying the toner from the tank portion to a developing section which includes a developing roller. The tank portion accommodates a bladed wheel having blades therein while the toner supply portion has a projection which protrudes into the radius of rotation of the blades. As the blades are rotated, the projection scrapes off the toner deposited on the blades to thereby feed it into the toner supply portion. The radius of rotation of the blades is substantially equal to or smaller than the inner radius of the tank portion, whereby the blades are prevented from pressing against the tank portion.
