In this device, the toner supplying portion includes an agitator member for agitating the toner within the toner supplying portion so as to prevent the toner from sticking to an inside wall of the toner supplying portion.
What is claimed is: 1. A toner supplying device for use in an image forming system, said device comprising:cleaner means for removing toner from a photosensitive medium of the image forming system so as to store the toner of the photosensitive medium in said cleaner means; and toner supplying means, integrally formed with said cleaner means, having a compartment for storing toner and a mechanism for supplying the toner of the compartment to a developing unit so that a toner image is formed on a copy sheet in accordance with an electromagnetic latent image on the photosensitive medium; said toner supplying means including agitator means for agitating the toner within the toner supplying means so as to prevent said toner from sticking to an inside wall of the toner supplying means, said agitator means being rotatable around a longitudinal axis of said agitator means, and said toner supplying means further including an oscillating member with a leading edge portion which comes into contact with an inside portion of said compartment of said toner supplying means when said agitator means is rotated, said oscillating member being arranged so as to transversely extend within said compartment of said toner supplying means, and said oscillating member being oscillated by said agitator means. 2. A device according to claim 1, wherein said agitator means is rotated in an interlocking manner by a drive motor for driving said toner supplying mechanism to supply the toner of said compartment to the developing unit.
BACKGROUND OF THE INVENTION The present invention generally relates to an image forming system, and more particularly to a toner supplying device of an image forming system, which device includes a cleaner portion for removing a residual toner from a photosensitive medium and an integrally formed toner supplying portion for supplying toner to a developing unit so that a toner image is formed on a copy sheet.
SUMMARY OF THE INVENTION Accordingly, it is a general object of the present invention to provide an improved toner supplying device of an image forming system in which the above described problems are eliminated.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an image forming system to which an embodiment of a toner supplying device according to the present invention is applied;
DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will now be given, with reference to FIG. 1, of a first embodiment of a toner supplying device according to the present invention. FIG. 1 shows an image forming system in which the toner supplying device of the present invention is provided. In FIG. 1, a photosensitive belt member 10 is rotatably supported by three rollers 11, and this photosensitive belt member 10 is rotated around a circumference thereof due to rotation of the rollers 11. Similarly to an image forming system which is known in the art, a static eliminator 12, a charging unit 13, a developing unit 14, a transfer unit 15, and a magazine 16 are provided at the surrounding portions of the photosensitive belt member 10 within the image forming system.
FIGS. 6A and 6B show operations performed by the flexible sheet part 47 of FIG. 5. As shown in FIG. 6A, the radial length "X" of the flexible sheet part 47 described above can be determined as being a distance "X1" between the center of the rotating shaft 48 and the farthest inside wall 32a of the toner supplying part 32. The thus determined radial length "X" allows the flexible sheet part 47 to come into contact with the inside wall of the toner supplying part 32 and to be resiliently deflected into a deflected condition when the agitator member 45 is rotated around the rotating shaft 48. When the radial length "X" of the flexible sheet part 47 in the deflected condition is equal to either "X2" or "X3" as shown in FIGS. 6A and 6B (X2, X3&lt;X1), a corresponding toner scraping force F2 or F3 needed to scrape the residual toner from the inside wall of the toner supplying part 32 varies in proportion to the deflection "Y2" or "Y3" of the flexible sheet part 47. Generally, the toner scraping force required to scrape the toner off the inside wall of the toner supplying part 32 varies depending on the deflection of the flexible sheet part 47 and depending on the modulus of elasticity of the flexible sheet part 47.
