ABSTRACT:
An image fixing device having a rotatable fixing member to fix a toner image formed on an image holding member by an image forming process such as electrophotographic process, electrostatic recording process, magneto-photographic process, etc. under pressure or heat application to the image holding member; a thin film member holding therein a parting or releasing agent; and a plurality of urging members to be press-contacted to the fixing member through the thin film member. The device has such effects that it exhibits satisfactory cleaning effect of the rotatable fixing member over a long period of time, enables the parting agent to be uniformly and stably applied onto the fixing member, and prevents an offset phenomenon from occurring by synergistic effects of the satisfactory cleaning and the uniform liquid application, thereby improving the life of the fixing roller to a remarkable extent.
