Abstract
A toner dispensing device for use in a developing apparatus of an electrophotographic copying machine. The device includes a toner tank mounted on the developing apparatus, a horizontal slit formed at a lower portion of the toner tank, a toner supplying plate which is adapted to reciprocate through the slit for supplying toner at constantly uniform rates from a plurality of openings formed in the same plate, and a stabilizing plate pivotally disposed in the toner tank for dividing the toner tank into upper and lower portions. When the toner supplying plate strikes in its return motion against the stabilizing plate, a predetermined amount of toner is supplied from the upper portion into the lower portion through openings formed in the stabilizing plate for maintaining a predetermined amount of toner in the lower portion at a uniform density.
