A thermal fixing apparatus, including a rotatable first member; a heater heating the first member; a rotatable second member forming a nip portion with the first member; and a pressurizing member disposed inside the first member, and having a contact surface with an inner surface of the first member. The pressurizing member includes a surface layer constituting the contact surface, and the surface layer comprises a diamond-like carbon film containing a hydrogen atom (H), a carbon atom (C) and a silicon atom (Si). 100&#xd7;(H)/((H)+(C)) is 5 or less. 100&#xd7;(Si)/((Si)+(C)) is 1 to 20. Between the contact surface and an inner circumferential surface of the first member, an oil film containing a fluorinated oil and a silicone oil is present.

Thermal fixing apparatus and image forming apparatus

A fixing device capable of stably performing a fixing operation for a long time is provided. The fixing device includes a cylindrical fixing belt and a heater. The fixing belt includes a resin layer forming an inner circumferential surface contactable with the heater. The heater includes a surface layer forming a sliding surface sliding on the fixing belt. The surface layer is an amorphous carbon film containing graphite particles. The sliding surface includes protrusions derived from the graphite particles. The protrusions have a distribution density of 50 to 2000 per 1 square millimeter of the sliding surface.

Fixing device and image forming apparatus

Provided is a method of producing an optical element forming mold, the method including forming a ta-C filmon a mold matrixfor an optical element forming mold by an FCVA process, in which the mold matrixis kept at a floating potential, a voltage is applied to a mold matrix-holding memberfor holding the mold matrix via insulating members (), and a magnetinternally provided in the mold matrix forms a magnetic field for applying a magnetic force in a normal direction of a transfer surface of the mold matrix so as to follow a magnetic force applied by a filter coil, thereby homogenizing the film quality.
