Electrophotographic apparatus with pre-exposure controlled according to photoconductor thinning |
摘要 |
An electrophotographic apparatus includes an electrophotographic photosensitive member; a charging member contactable to the photosensitive member for charging the photosensitive member at a charging position; exposure means for exposing the photosensitive member to electrically discharging the photosensitive member, wherein when a region of the photosensitive member discharged by the exposure means is at the charging position, a voltage-current characteristic between the charging member and the photosensitive member is detected; changing means for changing an incident light quantity to the photosensitive member from the exposure means.
