FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

A fixing device includes an endless belt member, a fixed member that is in contact with an inner circumferential surface of the belt member, a heating member configured to heat the belt member, and a pressing member including at least a pressing roller that includes an elastic surface layer and presses the belt member against the fixed member from an outer circumferential side of the belt member in such a manner as to form a fixing part through which a recording object carrying an unfixed image is made to pass. A center, in a direction of rotation of the pressing roller, of a contact part of the fixed member that is in contact with the pressing roller through the belt member resides at a position that is displaced toward an entrance side of the fixing part with respect to a center of rotation of the pressing roller.

主权项

1. A fixing device comprising:
an endless belt member; a fixed member fixedly provided and being in contact with an inner circumferential surface of the belt member; a heating member configured to heat the belt member; and a pressing member including at least a pressing roller that rotates when driven and includes an elastic surface layer, the pressing roller being configured to press the belt member against the fixed member from an outer circumferential side of the belt member in such a manner as to form a fixing part through which a recording object carrying an unfixed image is made to pass, the elastic surface layer undergoing elastic deformation when the fixing part is formed, wherein a center, in a direction of rotation of the pressing roller, of a contact part of the fixed member that is in contact with the pressing roller through the belt member resides at a position that is displaced toward an entrance side of the fixing part with respect to a center of rotation of the pressing roller.
