Fixing device

Abstract

<P>PROBLEM TO BE SOLVED: To prevent deformation of an end of a fixing belt at the time of power failure, while regulating movement of the fixing belt in an axial direction during normal operation. <P>SOLUTION: The fixing device 1 is provided with: the fixing belt 2; a pressure roller 4, a supporting body 5 provided in the fixing belt 2; a halogen lamp 6 provided in the fixing belt 2; a shielding plate 7 shielding the supporting body 5 from the halogen lamp 6 in the fixing belt 2; and a deviation regulating part 35 provided to be opposed to an end face in the axial direction of a portion nearer to the supporting body 5 side than the shielding plate 7 on the fixing belt 2 and regulating movement of the fixing belt 2 in the axial direction. The deviation regulating part 35 is not provided in a position opposed to the end face in the axial direction of a portion nearer to the halogen lamp 6 side than the shielding plate 7 on the fixing belt 2, but a clearance space 37 is formed in that position. <P>COPYRIGHT: (C)2010,JPO&INPIT
【課題】通常運転時における定着ベルトの軸方向への移動を規制しつつ、停電時における定着ベルトの端部の変形を防止する。 【解決手段】定着装置1は、定着ベルト2と、加圧ローラ4と、定着ベルト2内に設けられた支持体5と、定着ベルト2内に設けられたハロゲンランプ6と、定着ベルト2内において支持体5をハロゲンランプ6から遮蔽する遮蔽板7と、定着ベルト2のうち遮蔽板7よりも支持体5側の部分の軸方向端面に対向して設けられ、定着ベルト2の軸方向移動を規制する片寄り規制部35とを備えている。定着ベルト2のうち遮蔽板7よりもハロゲンランプ6側の部分の軸方向端面に対向する位置には、片寄り規制部35が設けられておらず、逃げ空間37が形成されている。 【選択図】図1
