    摘要: A method for coating of a developer comprises using a device having a vessel for storing a non-magnetic developer and magnetic particles, a developer holding member which conveys with rotation the non-magnetic developer to a latent image bearing member, a regulating member positioned on the side of the outlet of the above vessel for feeding the non-magnetic developer and arranged on the developer holding member with a gap formed therebetween, and a magnetic pole arranged on the side opposite to the regulating member through the intermediary developer holding member for forming a magnetic brush with the magnetic particles on the upstream side of the regulating member on the developer outlet side of said vessel; andforming a thin layer of the non-magnetic developer on the developer holding member, said magnetic particles having a magnetization of 30 emu/g or higher in the external magnetic field of 5000 oersted.

    摘要: A development apparatus has a developer supporting member having a magnet therein and a thickness controlling member for the developer, the developer being a magnetic one-component developer which is applied to the surface of the developer supporting member by means of the thickness controlling member, the applied surface of the developer supporting member being brought into a position opposed to a latent-image carrying member to develop the latent image thereon, the surface of the developer supporting member being roughened by sand blast treatment with irregularly shaped and/or sized particles.
