摘要： A fixing device of the present invention includes: an external heating belt which is to contact with a surface of a fixing roller so as to heat up the fixing roller; and a cleaning member (a scraper and/or cleaning pad) which is to contact with the external heating belt. The cleaning pad which is impregnated with silicone oil is to contact with a surface of the external heating belt, thereby applying the silicone oil (release agent) to the surface of the external heating belt. This makes it possible to prevent generation of an offset.

摘要： First, a first temperature difference and a second temperature difference are calculated. The first temperature difference is a difference between (a) a first detected temperature that is a current temperature of the fixing member and (b) a difference of a control target temperature for the fixing member. The second temperature difference is a difference between (a) the first detected temperature and (b) a past temperature of the fixing member which past temperature was detected a predetermined time earlier than the current time. Then, by reading out, from a table prepared in advance, an amount of power to be supplied to a heating member which amount corresponds to a combination of the first temperature difference and the second temperature difference, the amount of power to be supplied to the heating member is determined. In accordance with this amount of power determined, an actual amount of power supplied to the heating member is controlled. This makes it possible to simply and effectively suppress a temperature ripple of the fixing member.

摘要： An image recording medium that can be repeatedly used by removing the toner image has a three-layered structure formed of a heat-resistant resin sheet and a pair of releasing and light absorptive layers coated on both sides of the heat-resistant resin sheet. The releasing and light absorptive layer generates heat by absorbing laser so as to fuse and fix the toner image formed on the special sheet surface at the time of image forming, and assures pertinent releasing performance at the time of image removal so as to facilitate removal of the re-fused toner image. The image recording medium may have a five-layered structure in which each releasing and light absorptive layer is split into a light absorptive layer and a releasing layer. The image recording medium may have a three-layered structure formed of a light absorptive and heat-resistant resin sheet that is produced by adding an infrared absorbent to a heat-resistant resin sheet to serve as a heat-resistant sheet and a light absorptive layer, and a pair of releasing layers formed on both sides of the light absorptive and heat-resistant resin sheet.

摘要： A fixing roller includes: a core; an elastic layer made of an elastic material, formed around the core; and a resin layer made of fluorine resin, formed around the elastic layer. The fixing roller is designed such that the resin layer has a thickness of 40 μm or more, and the fixing roller meets a relation Tr≧Tc+60 or Tr≧Tc+75 where Tr (° C.) is a limit temperature obtained in a predetermined peeling test and Tc (° C.) is a temperature of the fixing roller at which a fixing process is performed. This allows the fixing roller used in an image forming apparatus with a high process speed to secure that the resin layer is less likely to be detached from the elastic layer.
