ABSTRACT:
A toner supplying mechanism for use in an imaging apparatus for forming a toner image. The development unit of the apparatus includes a development roller for attracting toner particles to be adhered onto a circumferential surface of a predetermined material. The toner cartridge member, provided at the upper side of the development roller, houses a multiplicity of toner particles to be supplied toward the development roller through an inclined inner wall of the development unit. A scraper member, having at least one rotating arm member on a predetermned shaft member, located between the development roller and the toner cartridge, scrapes the toner particles on the inner wall and feeds them toward the development roller. The development unit further includes an elastic sheet member, located on the inclined inner wall, whose lower edge portion is arranged to be flipped by the rotating arm member. The upper edge portion of the elastic sheet member is fixed to the inclined inner wall. Thus, it becomes possible to effectively supply toner from the toner cartridge toward the development roller.
