<P>PROBLEM TO BE SOLVED: To prevent deformation or deterioration in precision in a working process of a thin layered fixing roller and deterioration in strength, deformation or damage in the fixing roller at rotational driving force transmission. <P>SOLUTION: In the fixing unit provided with the fixing roller 211, a rotation transmission member 260 and an engaging member 270, the fixing roller 211 has an opening part 218 formed separated from an end part on at least one end part, the rotation transmission member 260 includes a notch 263 which is shallower than the thickness of the member 260, the engaging member 270 is provided with an opening engaging part 271 engaging with the opening part 218 and a notch engaging part 272 engaging with the notched part 263 and the width of the notch part 272 is formed to be wider than the width of the opening engaging part 271. Thus, the deterioration in strength, deformation, damage and deterioration in precision in the fixing roller is prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
