摘要:
A fixing device has a pair of rollers which are pressed against to each other to form a nip therebetween. A recording medium which carries a non-fixed image is clamped and conveyed by the nip to perform fixing. At least one of the pair of rollers has a mixture layer prepared by mixing a perfluoroelastomer having rubber elasticity and a fluorine resin.

The present invention provides a cleaning apparatus comprising a cleaning rotary member arranged to be pressed against a movable image bearing member, for removing residual toner on the image bearing member. Cleaning rotary member has a first elastic layer as an outer layer, and a second elastic layer disposed inside of the first elastic layer. Second elastic layer has a volume resistance smaller than that of the first elastic layer. The present invention further provides a cleaning roller comprising a core metal, a conductive layer disposed on the core metal and an insulation layer disposed on the conductive layer.
摘要:
An image forming apparatus for forming a toner image on a recording material applies a bias voltage having the same polarity as the toner to a core bar of a fixing roller. A fixing entrance guide is provided so that the recording material approaches or contacts the fixing roller when the recording material enters a contact-pressure region formed by the fixing roller and a pressing roller. Thus, offset of toner to the fixing roller is prevented.
