Description
第1〜第4の4つの画像形成部1Y・1M・1C・1Bkは、ベルト8の下側においてベルト移動方向に沿って所定の間隔をおいて配列されている。各画像形成部1Y・1M・1C・1Bkはレーザ露光方式の電子写真プロセス機構であり、それぞれ、矢印方向に所定の速度で回転駆動されるドラム型の電子写真感光体(以下、感光ドラムと記す)2を有している。各感光ドラム2の周囲には、一次帯電器3、現像装置4、一次転写ローラ5、ドラムクリーニング装置6が配置されている。各一次転写ローラ5はベルト8の内側に配置してあり、ベルト8を対応する感光ドラム2に圧接している。各感光ドラム2とベルト8との当接部が一次転写部である。7は各画像形成部1Y・1M・1C・1Bkの感光ドラム2に対するレーザ露光装置であり、入力する画像情報の電気的信号に対応した発光を行うレーザ発光手段、ポリゴンミラー、反射ミラー等で構成されている。 The first to fourth image forming units 1Y, 1M, 1C, and 1Bk are arranged at predetermined intervals along the belt moving direction on the lower side of the belt 8. Each of the image forming units 1Y, 1M, 1C, and 1Bk is a laser exposure type electrophotographic process mechanism. ) 2. Around each photosensitive drum 2, a primary charger 3, a developing device 4, a primary transfer roller 5, and a drum cleaning device 6 are disposed. The primary transfer roller 5 Yes disposed inside the belt 8 is in contact pressure of the belt 8 with the photosensitive drum 2 that corresponds. A contact portion between each photosensitive drum 2 and the belt 8 is a primary transfer portion. Reference numeral 7 denotes a laser exposure device for the photosensitive drum 2 of each of the image forming units 1Y, 1M, 1C, and 1Bk, which includes laser light emitting means that emits light corresponding to an electrical signal of input image information, a polygon mirror, a reflection mirror, and the like. Has been.
(3)定着装置の加熱定着動作
プリント信号に応じて制御回路部は定着モータ(不図示)を駆動する。その定着モータの駆動によって加圧ローラ32の芯金32aの長手方向端部に設けられた駆動ギア(不図示)が回転されることにより、加圧ローラ32は矢印方向に所定の周速度(プロセススピード)で回転する。その加圧ローラ32の回転は定着ニップ部Nを介して定着ローラ30表面に伝達され、これにより定着ローラ30は加圧ローラ32の回転に追従して矢印方向に回転する。
(3) Heating and fixing operation of the fixing device The control circuit unit drives a fixing motor (not shown) according to the print signal. By the fixing motor driving gear provided in the longitudinal end portions of the core metal 32a of the pressure roller 32 by a drive (not shown) is rotated, the pressure roller 32 is a predetermined peripheral speed in the direction of the arrow ( Rotate at process speed. The rotation of the pressure roller 32 is transmitted to the surface of the fixing roller 30 via the fixing nip portion N, whereby the fixing roller 30 follows the rotation of the pressure roller 32 and rotates in the direction of the arrow.
