In a method and system for handling of an endless belt for an electro-photographic printer or copier, an endless belt is borne with aid of a first, a second, and a third cylindrical body. 5 percent to about 30 percent dispersant; and, from about 25 percent to about 90 percent water. Thus, large charge capacitance values can be obtained compared to a similarly sized device using an ONO or Ta2O5 thin film dielectric while simultaneously simplifying the manufacturing process. An ECU of the motor drive apparatus controls the inverter such that an offset current is superimposed on at least one phase of the coil of the stator and a temperature of the permanent magnet provided at the rotor is raised. The judging unit changes the defocus control based on the determination result.
