A charging apparatus having a corona electrode is provided which exhibits high durability against ozone and moisture in the air, which can charge a surface of a photoreceptor drum stably throughout the life of an image forming apparatus, and which can be manufactured at a low cost. In a charging apparatus including corona electrode having a flat plate section and a pointed projection section, a support member, a shield case, and a grid electrode, a coating layer including a material different from the material of the corona electrode is formed at least on part of the surface of pointed projections constituting the pointed projection section.
