Abstract (en)
A developer carrier has concave portions regularly arranged on the surface thereof and being rotatable with a developer thereon. A contact member is made of an elastic rubber material, is in contact with the surface of the developer carrier, and vibrates with the rotation of the developer carrier. A value obtained by dividing a movement speed of the surface at the time of rotation of the developer carrier by a pitch of the concave portions in a peripheral direction of the developer carrier is smaller than the number of vibrations of the contact member when a loss tangent obtained by dividing a loss elastic modulus of the contact member by a storage elastic modulus is the greatest.
