ABSTRACT:
A developer material coating apparatus comprising a developer material coating unit for triboelectrically charging the developer material and electrostatically supplying the charged developer material to the support member in the developer material coating region, the developer material coating unit including a carry roller rotatable around a rotational axis thereof for carrying thereon and feeding the charged developer material to the developer material coating region, and a support member feeding unit for feeding the support member to the developer material coating region while carrying the support member thereon, the support member feeding unit having a coating plane in the developer material coating region on which the support member is disposed so as to be electrostatically coated with the developer material and a guide unit for feeding the support member along the coating plane in a predetermined feeding direction, and wherein the carry roller is disposed at a predetermined interval away from the coating plane such that the direction of the rotational axis of the carry roller is intersected obliquely at a predetermined angle to the feeding direction of the support member on the coating plane of the support member feeding unit.
