Claims (6)
- 화상 정보를 처리하는 화상 데이터 처리 수단과, 이 수단에 의해 처리된 화상 데이터에 의해 감광체 상에 정전 잠상을 형성하는 잠상 형성 수단과, 상기 감광체의 비화상 영역에 잠상 화상을 부여하는 잠상 화상 부여 수단과, 상기 잠상 형성 수단에 의해 형성된 정전 잠상 및 상기 잠상 화상 부여 수단에 의해 부여된 잠상 화상을 토너에 의해 현상하는 현상 수단을 마련한 화상 형성 장치에 있어서,상기 잠상 화상 부여 수단은 상기 감광체상의 비화상 영역에 잠상을 부여할 수 없는 잠상 불가 영역을 설정하는 수단을 구비하는 것을 특징으로 하는 화상 형성 장치.
- 제1항에 있어서, 상기 잠상 불가 영역을 설정하는 수단은 상기 잠상 불가 영역을 상기 감광체의 주주사 방향에 따라 임의의 영역에 설정하는 수단인 것을 특징으로 하는 화상 형성 장치.
- 제1항에 있어서, 상기 잠상 불가 영역을 설정하는 수단은 상기 잠상 불가 영역을 상기 감광체의 주주사 방향에 따라 복수 개소 설정할 수 있는 수단인 것을 특징으로 하는 화상 형성 장치.
- 제1항에 있어서, 상기 잠상 불가 영역을 설정하는 수단은 상기 감광체에 대하여 마련되는 분리톱에 대응하는 영역에 상기 잠상 불가 영역을 설정하는 수단인 것을 특징으로 하는 화상 형성 장치.
- 제1항 내지 제4항 중의 어느 한 항에 있어서,상기 잠상 화상 부여 수단이 상기 감광체의 비화상 영역에 부여하는 잠상 화상은 클리닝 블레이드 말림 방지 유형인 것을 특징으로 하는 화상 형성 장치.
- 제1항 내지 제4항 중 어느 한 항에 있어서,상기 잠상 화상 부여 수단이 상기 감광체의 비화상 영역에 부여하는 잠상 화상은 토너 농도 조절용의 유형인 것을 특징으로 하는 화상 형성 장치.
