Abstract

1. TECHNICAL FIELD OF THE INVENTION

The present invention relates to an image forming apparatus of an electrophotographic processor which is integrated with a developing device without separating the cleaner part of the present invention.

2. Technical problem to be solved by the invention

An object of the present invention is to provide an image forming apparatus of an electrophotographic processor that can reuse recycled toner by a cleaner.

3. Summary of Solution to Invention

According to an aspect of the present invention, one side of the photosensitive drum is a transfer unit for transferring a toner image on the surface of the photosensitive drum to a recording paper, and the other side of the photosensitive drum is a charger for electrically charging a charge layer on the surface of the photosensitive drum, and the charger One side of the developer is provided with a developing device for forming an image, the upper surface of the developer is a toner loading portion for storing the toner, the lower surface of the inside of the developer supply roller for supplying the stirred toner to the developing roller side, and One side of the supply roller is a developing roller for developing the toner on the electrostatic latent image formed on the surface of the photosensitive drum, one side of the upper end of the developing roller is a doctor-bleed that regulates the toner formed on the surface of the developing roller to a constant height; One side of the developer is a cleaner for removing toner remaining on the surface of the photosensitive drum, and one side of the developer is electrically Exposure will add installed to form an electrostatic latent image on the charged photosensitive drum surface.

4. Important uses of the invention

The present invention can maximize the efficiency of toner use because the toner collected by the cleaner can be reused, and is not spaced by installing the cleaner in the developing unit without installing the cleaner in the main body of the machine. By reusing toner, it is possible to prevent contamination of the inside of the machine body and environmental pollution, and also to install a charger between the photosensitive drum and the developer and to install a cleaner inside the developer, thereby miniaturizing and reducing the weight of the product.
