| 摘要 |
A developer material coating apparatus for electrostatically coating developer material on a support member in a developer material coating region to form a developer sheet, comprising a counter electrode roller for feeding the support member through the developer material coating region while carrying the support member thereof, a carry roller for triboelectrically charging the developer material and electrostatically supplying the charged developer material to the support member disposed in the developer material coating region, at least one array of electrodes arranged along the inner surface of the counter electrode roller and a control unit for selectively supplying said electrodes with a voltage having an opposite polarity to that of the charged developer material to thereby coat the developer material on a desired portion of the support member.
