Abstract

A ferromagnetic layer is bonded to, or coated on, or in other manner applied to, the surface of a heatable fuser member for fusing dry toner in an image forming device. The ferromagnetic layer promotes inductive heating of the heatable fuser member based on high hysteresis loss exhibited when the ferromagnetic layer is exposed to a magnetic field created by the current flowing through an induction coil or other like device. Suitable materials for the ferromagnetic layer are those which exhibit a high coupling efficiency to the imposed magnetic field. A result is substantially controllable, consistent heating of the heatable fuser member to fuse dry toner onto or into the image bearing surface of an image receiving medium.

Description

technical field [0001] The present invention relates to systems and methods for fusing toner to an image receiving medium in an image forming apparatus. Background technique [0002] In image forming apparatuses, various systems and methods have traditionally been used to fuse toner particles on image bearing surfaces of various image receiving media. Typically, these systems and methods include a heated pressing surface that can be used to melt and press dry toner to fuse the image to the image receiving medium, in a prior step to forming an image on or in the image bearing surface, The dry toner is deposited on the image bearing surface of the image receiving medium. [0003] In an image forming apparatus, typical conventional systems and methods for fusing dry toner on or in the image bearing surface of an image receiving medium include, for example, using what is commonly referred to as a heated roll fusing apparatus to provide A heated pressing surface that can be use...
