The charger charges the photosensitive member and includes a charging wire and a grid electrode, which is provided between the charging wire and the photosensitive member, and which has an opening area in a surface opposing the photosensitive member. The frame supports the photosensitive member and the charger. The block member is provided between the charging wire and an end portion of the grid electrode in a longitudinal direction thereof and prevents a marginal area of the grid electrode from facing the charging wire in a direction with a minimum distance therebetween, the marginal area being defined between an end of the grid electrode and an end of the opening area.
