Description
前記課題を解決するため、本発明の定着装置は、軸線方向に一対で配設された保持部によって両端部が周回可能に摺接保持された定着スリーブと、前記定着スリーブを加熱する加熱源と、前記一対の保持部の間において前記定着スリーブの内周面に当接したベース部材と、前記定着スリーブと対向して配置され、前記定着スリーブと当接した状態で前記ベース部材との間でニップ部を形成すると共に、当該当接状態で回転駆動することで前記定着スリーブを従動回転する加圧部材と、前記定着スリーブの両端部に配設されたラビリンス構造を有するシール部と、を有することを特徴とする。 In order to solve the above-mentioned problem, a fixing device of the present invention includes a fixing sleeve in which both ends are slidably held by a pair of holding units disposed in the axial direction so as to be able to rotate, and a heating source that heats the fixing sleeve. A base member abutting on the inner peripheral surface of the fixing sleeve between the pair of holding portions, and a base member disposed opposite to the fixing sleeve and in contact with the fixing sleeve; A pressure member that forms a nip portion and is driven to rotate the fixing sleeve by being rotationally driven in the contact state; and a seal portion having a labyrinth structure disposed at both ends of the fixing sleeve. it shall be the features a.
定着スリーブ21の温度は、温度検知手段としてのサーモパイル27によって、また加圧ローラ22の温度は、温度検知手段としてのサーミスタ29によって、それぞれ検知されるようになっている。その他、定着スリーブ21から用紙を分離する分離部材28と、加圧ローラ22を定着スリーブ21へ加圧する加圧手段等が設けられている。 The temperature of the fixing sleeve 21, the thermopile 27 as temperature detecting means and the temperature of the pressure roller 22, the thermistor 29 as a temperature detecting means, is adapted to be detected, respectively. In addition, a separating member 28 for separating the sheet from the fixing sleeve 21, a pressing unit for pressing the pressing roller 22 to the fixing sleeve 21, and the like are provided.
このため、定着スリーブ21とニップ形成部材80の摺動部分におけるスティック・スリップ現象で異音が発生すると、当該異音が前記隙間65から外部に漏れて騒音になっていた。また定着スリーブ21の内部の高温が前記隙間65から外部に逃げることでハロゲンヒータ70の消費電力に無駄が発生していた。 For this reason, when an abnormal noise is generated due to a stick-slip phenomenon in a sliding portion between the fixing sleeve 21 and the nip forming member 80, the abnormal noise leaks to the outside from the gap 65 and becomes noise. Further, since the high temperature inside the fixing sleeve 21 escapes from the gap 65 to the outside, the power consumption of the halogen heater 70 is wasted.
