写真系プリンタ用用紙走行部に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a paper transport unit for an electrophotographic printer, in particular, to a photosensitive drum and a transfer charger unit (transferring toner on the drum onto paper). This invention relates to a paper running section for electrophotographic printers for feeding paper.
従来の電子写真系プリンタ用用紙走行部は、用紙ガイド

境下（特に低湿）でトナー散り（前転写）が起こるとい
う欠点があった。However, since the above-mentioned conventional paper running section for electrophotographic printers is formed of rubber rollers or carbon rubber rollers, the cost of rubber rollers (including carbon-containing rollers) is high, and in terms of quality, carbon-containing rollers are not suitable. Due to unstable factors, toner scattering (pre-transfer) inevitably occurs under certain environments (especially low humidity).

にアルミ製の送りローラを有して構成される。The paper running section for an electrophotographic printer of the present invention is configured to include an aluminum feeding roller on one side of the paper feeding roller in order to prevent toner scattering (pre-transfer).
次に、本発明の実施例について、図面を参照して説明す
る。Next, embodiments of the present invention will be described with reference to the drawings.
