Abstract
PURPOSE:To stabilize the supply rate of toner by providing a toner supply roll, formed by providing a foamed material layer around an elastic material layer, near a throw-in hole for toner. CONSTITUTION:In the bottom part of housing 1 of the toner supplier, throw-in hole 2 is opened, and over this throw-in hole 2, toner supply roll body 3 is provided. This roll body 3 has the double-layer structure of elastic material layer 3a which shaft 4 penetrates in the center and foamed material layer 3b provided around it. As roll body 3 rotates, scrape-off projection 5 at the opening edge of throw-in hole 2 bites into foamed material layer 3b and toner with which layer 3b is impregnated falls on a developing device from throw-in hole 2.
