Abstract

1.청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

본 발명은 장마철 또는 습기가 많은 지역에서 사용시에 현상기 내부로 유입되는 습기를 방지하므로서 고해상도의 화상을 형성할 수 있는 전자사진 프로세서의 화상 형성 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus of an electrophotographic processor capable of forming a high resolution image while preventing moisture from entering the developer when used in a rainy season or a humid area.

2.발명이 해결하려고 하는 기술적 과제2. Technical problem that the invention tries to solve

본 발명은 주위 환경(습도 및 온도가 높을시 또는 유럽지역)에 영향을 받지 않는 전자사진 프로세서의 화상 형성 장치를 제공하는데 있다.The present invention provides an image forming apparatus of an electrophotographic processor that is not affected by the surrounding environment (when the humidity and temperature are high or in the European region).

3.발명이 해결방법의 요지3. Summary of Solution

본 발명은 토너를 적재하는 토너적재부와 하우징으로 구성된 현상기 내부에는 토너의 이송 및 교반시키는 교반기와, 상기 감광드럼 표면의 정전잠상에 토너을 현상시키는 현상롤러와, 상기 현상롤러의 표면에형성된 토너를 균일한 높이로 규제하는 독터블레이드와, 외부에서 상기 현상기 내부로 유입되는 습기를 제거하는 습기제거부와, 상기 독터블레이드를 보호하고, 토너가 외부로 유출되는 것을 방지하는 커버로 구성된 것이다.The present invention includes a stirrer for transporting and stirring the toner, a developing roller for developing the toner on the electrostatic latent surface of the photosensitive drum, and a toner formed on the surface of the developing roller. The doctor blade is regulated to have a uniform height, a moisture removing unit for removing moisture introduced into the developer from the outside, and a cover for protecting the doctor blade and preventing the toner from leaking to the outside.

4.발명의 중요한 용도4. Important uses of the invention

본 발명은 독터블레이드와 커버 사이에 습기제거부를 설치하므로서 상기 전자사진 프로세서를 상요시에 주위환경(즉, 습도가 높다든지 또는 온다가 높다든지 또는 유럽지역)에 영향을 받지 않으며, 또한 현상기 내부에서 토너가 굳지 않아 현상롤러에서 감광드럼 측으로 토너가 원활히 이송되며, 상기와 효과로 사용자가 원하는 고해상도의 화상을 형성할 수 있으며, 이로인해 제품의 신뢰성을 향상시킬 수 있는 효과가 있다.The present invention is provided with a dehumidifying portion between the doctor blade and the cover so that the electrophotographic processor is not affected by the surrounding environment (ie, high humidity or high temperature or European region) at all times, and also inside the developer. The toner is not hardened so that the toner is smoothly transferred from the developing roller to the photosensitive drum side, and the above-described effect can form a high resolution image desired by the user, thereby improving the reliability of the product.
