Abstract
Official abstract text for this publication.
According to an embodiments, a fixing device includes: an endless fixing member; a heating unit that is provided inside an inner peripheral surface of the fixing member; and a nip forming unit that comes into press-contact with a rotationally driven pressing member with the fixing member interposed therebetween to form a nip. The nip forming unit has a shape in which a center of a contact surface protrudes toward the pressing member compared to both ends. The nip forming unit has a protruding amount at a center toward the pressing member compared to both ends of the nip forming unit in no-load state is set to be less than a bent amount of the nip forming unit when the nip forming unit comes into press-contact with the pressing member with the fixing member interposed therebetween.

1 - 9 . (canceled) 10 . A fixing device comprising: an endless fixing member; a heating unit that is provided inside an inner periphery surface of the fixing member and that heats the fixing member; a nip forming unit that is provided inside the inner periphery surface of the fixing member and that comes into press-contact with a rotationally driven pressing member with the fixing member interposed therebetween so as to form a nip to which a recording sheet is conveyed, wherein both ends of the nip forming unit in a recording sheet width direction are fixed and supported, the nip forming unit includes a supporting member whose both ends in the recording sheet width direction are fixed and supported; and a contact member that is fixed to the supporting member and comes into contact with the pressing member with the fixing member interposed therebetween, and a length of the contact member at the center in the recording sheet width direction, the length being a length in a direction perpendicular to the surface of the recording sheet, is longer than a length at both ends in the recording sheet width direction.
