A cleaning device capable of cleaning a rotary head without discharging static electricity to a magnetic head is provided. The cleaning device comprises a protruding shaft-like supporting member provided at a position in a housing facing a portion of the outer peripheral surface of a rotary drum and opposite a portion in contact with a magnetic tape, and a cylindrical cleaning member supported at the upper end of the supporting member. The supporting member is configured with a metal material, and is electrically connected with the housing. The cleaning member is made of an electrically conductive resin in which carbon particles are contained. When and while the outer peripheral surface of the cleaning member is in contact with the outer peripheral surface of the rotary drum, the cleaning member is electrically connected with the housing through the supporting member.
