摘要： A fixing method for fixing an unfixed toner image formed on a recording material by transporting the recording material to a contact portion between a fixing roller and a pressurizing mechanism for pressurizing the surface of the fixing roller is arranged such that the fixing roller surface temperature and the pressurizing mechanism surface temperature at the contact portion while the recording material is being transported therethrough are controlled to fall within a non-offset region in which a sufficient fixing strength for fixing toner onto the recording material can be ensured without generating a high temperature offset, said non-offset region being defined by a critical border line obtained from a function of a fixing roller surface temperature and a pressurizing mechanism surface temperature. According to the described fixing method, an occurrence of an offset can be prevented without an application of an oil, and a toner fixing inferior can be prevented.

摘要： A fixing device which can reduce an overshoot of the surface temperature of a main heating section without lengthening a warming-up period of time, an image forming apparatus equipped therewith, and a recording medium on which is recorded the temperature control program are provided. In a standby mode, control is performed to stop an operation of a halogen lamp which is an internal heat source, when a surface temperature of a heating roller reaches a certain temperature lower than a target temperature, or when the operating period of time of the halogen lamp reaches a certain period of time. By so doing, as the heating roller ceases to be heated at a point at which it reaches a temperature lower than the target temperature, it is possible to reduce the overshoot of the surface temperature of the heating roller.

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.

摘要： A fusing device (23) has heat reflectors (238) and (239) positioned in consideration of the fact that convective heat loss from respective outer surfaces of the heat reflectors (238) and (239) depends on orientation of the outer surfaces. More specifically, each of the heat reflectors (238) and (239) are positioned so as to have a convective heat transfer coefficient η of up to 0.9. The convective heat transfer coefficient η is given by the following expression: η=(Su+0.77Sh+0.54Sd)/(Su+Sh+Sd), were Su is a projected area of an outer surface of each of the heat reflectors on an upper horizontal plane, Sh is a projected area of the same on a vertical plane, and Sd is a projected area of the same on a lower horizontal plane.
