摘要： A fixing device of the present invention is arranged so that: (i) at least both ends of a planar heat-generating member come close to or touch an outer surface of a fixing roller, said both ends being in a circumferential direction when viewed in an axial direction of the fixing roller; and (ii) the planar heat-generating member has, in the vicinity of both the ends, shapes formed gently with respect to the outer surface of the fixing roller when viewed in the axial direction. An almost whole inner surface area of the fixing belt wound around the planar heat-generating member and the fixing roller touches the planar heat-generating member or the fixing roller. The fixing belt is naturally formed, without being distorted at an area where the fixing belt touches the heating member. This allows a fixing device using a planar heat-generating belt type fixing method, which provides a short warm-up time, to be excellent in heat efficiency, consume less power, and have a fixing belt which does not slip easily.

摘要： Provided is a fixing apparatus employing an external heating method in which a scratch on a belt member and slippage of the belt member are prevented. The fixing apparatus includes: a fixing roller; a pressure member pressed against the fixing roller; an endless belt which is rotatably supported and contacts the fixing roller surface for heating the fixing roller; and heating means for heating the endless belt. By passing a recording material through a nip between the fixing roller and the pressure member, the fixing apparatus fixes an unfixed toner image on the recording material on which the unfixed toner image is transferred. The fixing apparatus further includes a cleaning member for removing dirt adhered to a surface of the endless belt by contacting the surface of the endless belt in a region where the endless belt is not supported.

摘要： An object of the present invention is to provide a charging roller (i) which includes a rubber member whose surface is subjected to a hardening treatment using a solvent containing at least an isocyanate compound and (ii) which can prevent leakage of an ionic conductive agent even if the charging roller is placed under conditions of high temperature and high humidity for a long time. The charging roller is made by forming a rubber layer on a metal core. The rubber layer is an epichlorohydrin based rubber base material to which an ionic conductive agent is added, the rubber layer being subjected to a surface treatment by applying a solution containing the isocyanate compound and heating it. This surface treatment is carried out under such conditions that a coefficient of dynamic friction at a contact portion between the rubber layer and a photoreceptor becomes 0.4 or less.
