A charging apparatus for electrically charging a chargeable member while magnetic particles contact to the chargeable member, includes first and second magnetic particle carrying members, the second being downstream of the first with respect to a magnetic particle feeding direction at an opposed portion where the first member and the chargeable member oppose each other. The apparatus also includes a regulating portion for regulating the amount of the magnetic particles carried on the first member, at a position upstream of the opposed portion, and first and second positioning portions for regulating movement of the first and second members. The first portion regulates the first member against movement in a moving direction of the chargeable member, and the second portion regulates the second member against its movement in a direction of contact to the chargeable member while permitting movement in the direction of movement of the chargeable member.
