Abstract
1. 청구범위에 기재된 발명이 속한 기술 분야1. Technical field to which the invention described in the claims belongs
본 발명은 현상롤러의 상부에 고탄성 고무로 형성된 규제롤러를 설치하여 현상롤러 표면의 토너층을 1층 이하로 균일하게 규제할 수 있는 현상롤러의 토너층 두께 규제 장치에 관한 것이다.The present invention relates to a toner layer thickness regulating device of a developing roller capable of uniformly regulating the toner layer on the surface of the developing roller to one layer or less by providing a regulating roller formed of a high elastic rubber on the top of the developing roller.
2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention
본 발명은 독터-블레이드를 사용하지 않고, 고탄성 고무로 형성된 규제롤러를 사용하여 현상롤러 표면의 토너층을 1층 이하로 규제할 수 있는 현상롤러의 토너층 두께 규제 장치를 제공하는데 있다.The present invention is to provide a toner layer thickness regulating device for a developing roller which can regulate the toner layer on the developing roller surface to one layer or less by using a regulating roller formed of a highly elastic rubber without using a doctor-blade.
3. 발명의 해결방법의 요지3. The point of the solution of the invention
본 발명은 일정한 주속으로 회전하는 감광드럼과, 상기 감광드럼의 표면을 전기적으로 균일하게 대전시키는 대전롤러와, 상기 감광드럼상의 정전잠상에 토너 화상을 형성시키는 현상롤러와, 토너를 전기적으로 균일하게 교반시키는 교반기와, 상기 현상롤러 표면에 형성된 토너층을 1층 이하로 균일하게 규제시키는 규제롤러와, 상기 감광드럼에 현상되지 않는 현상롤러 표면의 잔류토너를 제거하는 리셋-블레이드와, 상기제거된 잔류토너를 교반기 측으로 이송시키는 스폰지롤러로 구성된 것이다.A developing roller for forming a toner image on the electrostatic latent image on the photosensitive drum; a developing roller for uniformly charging the surface of the photosensitive drum in an electrically uniform manner; A regulating roller uniformly regulating the toner layer formed on the developing roller surface to one layer or less; a reset blade for removing residual toner on the surface of the developing roller that is not developed on the photosensitive drum; And a sponge roller for conveying the residual toner to the agitator side.
4. 발명의 중요한 용도4. Important Uses of the Invention
본 발명은 현상롤러 표면에 형성된 토너층을 1층 이하로 항상 균일하게 규제할 수 있기 때문에 전사효율을 높일 수 있어 고해상도의 화상을 형성시킬 수 있으며, 전사공정 후의 잔류 토너가 거의 없기 때문에 크리닝장치가 필요없는 크리너레스(cleaner-less) 현상장치를 구현할 수 있는 효과가 있다.Since the toner layer formed on the surface of the developing roller can always be uniformly regulated to be equal to or less than one layer, the transfer efficiency can be increased and a high-resolution image can be formed. Since there is almost no residual toner after the transferring step, There is an effect that a cleaner-less developing apparatus can be realized.
