Abstract
An image forming apparatus capable of reducing white streaks in gray images and an image forming method using the same are provided. The image forming apparatus including a charging means, a developing means, a transferring means, and a discharging means which are arranged in sequence around a monolayer type electrophotographic photoconductor. The charging means is a means for positively charging the surface of the monolayer type electrophotographic photoconductor, and the pre-charging means has a conductive brush composed of a conductive substrate and conductive brush filaments and is arranged between the charging means and the discharging means. The conductive filaments on the surface of the photoconductor have a bending ratio that is calculated so that the conductive brush filament tips are properly curved near the surface of the photoconductor so as to reduce abnormal discharge between the conductive brush and the surface of the photoconductor.
