Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

본발명은 전자사진 방식을 사용하여 인쇄를 행하는 화상형성장치의 현상기에 있어서 현상기 내의 토너 흐름을 원활하게 하여 선명하고 깨끗한 화상을 얻을 수 있도록 한 현상기 내의 토너 공급장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toner supply apparatus in a developing apparatus in which a toner flow in a developing apparatus is smoothed and a clear and clean image can be obtained in a developing apparatus of an image forming apparatus which prints using an electrophotographic method.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

본 발명은 현상기의 내부에 설치된 공급롤러 상측에 있는 토너의 흐름을 자연스럽게 유지하여 토너의 대전을 원활하게 하는 화상형성장치의 현상기 내의 토너 공급장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention provides a toner supply apparatus in a developing unit of an image forming apparatus which facilitates charging of toner by naturally maintaining a flow of toner above a supply roller provided inside the developing unit.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명은 화상형성장치의 현상기는 상부에는 토너를 저장하기 위한 토너하우징과, 상기 토너하우징에는 일측의 공급롤러로 토너를 교반시켜 이송시키는 에지테이터(agitator)와, 상기 현상기 내부의 하부프레임에는 상기 교반된 토너를 현상롤러 측으로 공급하는 공급롤러가 설치되며, 상기 공급롤러의 일측은 상기 감광드럼 표면에 형성된 정전잠상에 상기 토너를 현상하는 현상롤러가 설치되며, 상기 현상롤러와 공급롤러의 상부 사이에 토너의 이동을 위한 통로를 이루도록 이격되어 있는 유동보조기구와, 상기 현상롤러의 상단부에는 토너를 양을 일정한 높이로 균일하게 규제하는 블레이드가 설치된 것을 특징으로 한다.The developing device of the image forming apparatus includes: a toner housing for storing toner on an upper portion; an agitator for agitating and transporting the toner by a supply roller on one side; and a lower frame inside the developer. A supply roller for supplying the agitated toner to the developing roller side is installed, and one side of the supply roller is provided with a developing roller for developing the toner on an electrostatic latent image formed on the surface of the photosensitive drum, between the developing roller and an upper portion of the supply roller. The flow aid mechanism is spaced apart to form a passage for the movement of the toner, and a blade for uniformly regulating the amount of the toner to a certain height is installed at the upper end of the developing roller.
