画像形成装置

Abstract

<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which good quality double-sided printing that ensures uniform glossiness on the surface and back of paper is realized by a relatively simple configuration without making a printing control sequence complex. <P>SOLUTION: The image forming apparatus includes: a printing path X extending from a photoreceptor drum 4 via the fixing device 10 and used for printing an image onto paper P; a return path Y along which the paper P subjected to printing on one side is returned in the upstream of the photoreceptor drum 10 located on the printing path X; an inverting mechanism section 16 by which the paper P passed through the printing path X is inverted back to front and guided to the return path Y; and a control means 21 for exerting control such that when glossiness priority of double-sided print mode, in which priority is given to glossiness for both-sided printing, is set by a setting means 25, the operation of the inverting mechanism section 16 is stopped only for a predetermined period of time, and paper subjected to printing on one side is exposed outside the apparatus and naturally cooled. <P>COPYRIGHT: (C)2006,JPO&NCIPI
【課題】 比較的簡単な構成で、かつ印刷制御シーケンスも複雑化することなく、用紙の表裏で光沢度が均一化された品質の良い両面印刷が可能な画像形成装置を提供する。 【解決手段】 感光体ドラム4から定着装置10を経由して用紙Pに画像を印刷する印刷経路Xと、片面印刷後の用紙Pを印刷経路Xの感光体ドラム10よりも上流側に帰還させる戻り経路Yと、印刷経路Xを通過した用紙Pを表裏反転して戻り経路Yに導入する反転機構部16とを備えており、設定手段25により両面印刷時の光沢度を重視する光沢度重視両面印刷モードが設定された場合には、これに応じて反転機構部16の動作を所定時間だけ停止させて片面印刷後の用紙を機外に露呈して自然冷却する制御手段21を備えている。 【選択図】 図1
