ABSTRACT:

FIELD OF THE INVENTION AND RELATED ART
The present invention relates to a recycling method of a toner supply container for supplying toner into a main assembly of an image forming apparatus such as an electrophotographic copying machine, an electrophotographic printer or the like, the toner container being detachably mountable to a main assembly of the image forming apparatus.
In an electrophotographic image forming apparatus such as an electrophotographic copying machine, an electrophotographic printer or the like, fine toner powder is used as a developer. When the toner in the main assembly of the apparatus is consumed, the toner is supplied into the main assembly using a toner supplying container, which is detachably mountable to a main assembly of the electrophotographic image forming apparatus.
When the toner is supplied into the main assembly, a stirring and feeding member in the toner supply container is rotated by the main assembly, so that the toner is fed to gradually feed the toner through the toner supply opening to fill the main assembly.
It is desired that the toner supply container be reused after the toner has been discharged therefrom. In this case, it is desirable that before the toner is refilled into the container, the toner container is easily cleaned with high efficiency.
SUMMARY OF THE INVENTION
Accordingly, it is a principal object of the present invention to provide a recycling method of a toner supply container wherein the container is efficiently and easily cleaned after the toner is supplied into the main assembly.
It is another object of the present invention to provide a recycling method of a toner supply container by which resources and energy can be saved.
It is a further object of the present invention to provide a recycling method of a toner supply container wherein the container can be recycled substantially up to a new product.
These and other objects, features and advantages of the present invention will become more apparent upon a consideration of the following description of the preferred embodiments of the present invention taken in conjunction with the accompanying drawings.
