Title: Toner supplying container
Inventor: ISHII YOSHIKO
IPC: G03G15/08
Filed: 1992-12-23
Abstract: PURPOSE:To cause stored toner to hardly receive the influence of heat generated from a heat source even when a toner supply container is set near the heat source by making the structure of the toner supply container double structure consisting of an outer cylinder part and an inner cylinder part. CONSTITUTION:The toner supply container 1 has the double structure consisting of the outer cylinder part 6 and the inner cylinder part 7. The inner cylinder part 7 is constituted of a material whose heat conductivity is poor such as a synthetic resin. The outer cylinder part 6 is constituted of a material whose heat conductivity is excellent such as aluminum copper. The outer cylinder part 6 is constituted of the material having higher heat conduction coefficient than the inner cylinder part 7. The heat generated from a fixing device 5 is conducted to one end of the outer cylinder part 6, but the outer cylinder part 6 is made excellent in the heat conductivity, so that the heat conducted to the one end is quickly conducted to the aperture 8 side, and discharged from this side. Furthermore, since the inner cylinder part 7 is poor in the heat conductivity, the heat is hardly conducted to the toner in the inner cylinder part 7 and the toner is hardly melted.
