In an electrophotographic apparatus, there is disclosed a developing device and a rinsing device which use an improved roller. The roller comprises a stationary magnetic member including a plurality of magnetic poles, a non-magnetic rotatable member provided around the magnetic member so as to rotate along the outer periphery of the magnetic member, and a magnetic brush of magnetic particles formed on the outer surface of the rotatable member. By rotation of the rotatable member, the magnetic brush, which is imbued with a developing or rinsing liquid, will feed the liquid to the developing section or the rinsing section.
