A charging device is formed of a member to be charged, a charging member disposed so as to form a nip with the member to be charged, and electroconductive particles disposed so as to be present at the nip between the photosensitive member and the member to be charged. A uniform direct injection charging performance is realized by providing the charging member with a fine network-textured surface having concave cells giving a total cell edge perimeter per unit area of 15 mm/mm2 to 60 mm/mm2.
