Abstract

PURPOSE: To form images having sufficient image densities and yet having no unevenness by providing a specific developer replenishing member within the developer vessel on developing roller in developing of electrophotography using one component type developer composed of non-magnetic toner.
CONSTITUTION: In the developing device of developing the electrostatic latent images on a recording medium 7 by depositing and conveying the non-magnetic toner 13 in a developer vessel 12 on a developing roller 8 turning in the arrow direction while defining its quantity with a doctor knife 14, a developer replenishing member 16 is installed within the developer vessel 12. The replenishing member 16 is formed by securing plural protrusions 18 to the shaft 17 which is made movable in the axial direction of the developing roller 8. A follower 19 is secured to one end of the shaft 17 and its bottom end is fitted into the waveform groove 21a of the cam 21 of the roller 8. Hence, as the roller 8 rotates, the protrusions 18 are reciprocated in the arrow direction by way of the follower 19 and shaft 17 to collapse the toner having bridged in the vessel 12 and eliminate its biasing, whereby the toner supply to the roller 8 is made smooth.
