摘要：
An electrophotographing method using a corona charging device having areas with and without a grid. Prior to at least a second exposure step, a charging step is effected using both areas relative to the grid. A voltage applied to the grid in the second charging is lower than that in the first charging, and lower than a potential of a non-image region of the photosensitive body.
