Abstract:
The image forming apparatus includes a photosensitive drum and a light emitting device. In the rotational axis direction of the photosensitive drum, the width of the weak light exposure region on the photosensitive drum in which an exposing device emits weak light is larger than the width of a region corresponding to the width of a recording medium on which an image is formed, but smaller than the width of a region on the photosensitive drum charged by a charging roller.
