3. 발명의 해결방법의 요지3. Summary of Solution to Invention
감광체를 대전시키고 화상노광시켜서 정전잠상을 형성하고 이 정전잠상을 현상바이어스전압이 인가된 상태로 현상하는 것으로 이루어진 전자사진법에 있어서, 상기한 현상바이어스전압을 그 극성이 감광체의 대전극성과 동일하며 또한 광감쇠특성곡선의 고노광량영역근사곡선과 저노광량영역근사곡선과의 교차점에 상당하는 전위(EH)보다도 높은 전위로 설정하는 것을 특징으로 하는 전자사진법이다.In an electrophotographic method in which a photosensitive member is charged and an image is exposed to form an electrostatic latent image, and the electrostatic latent image is developed with a developing bias voltage applied thereto, the developing bias voltage has the same polarity as that of the counter electrode of the photosensitive member. The electrophotographic method is characterized by setting the potential higher than the potential E H corresponding to the intersection of the high exposure region approximation curve and the low exposure region approximation curve of the light attenuation characteristic curve.
