Abstract: An image forming apparatus includes a resistive heat generator, a temperature detector, and a power controller that detects a temperature-resistance property of the resistive heat generator before the resistive heat generator is used when the resistive heat generator is removably installed. The power controller obtains power supplied to the resistive heat generator and a change in a temperature of the resistive heat generator, that is detected by the temperature detector, while the power controller supplies the power at a predetermined power duty cycle for adjustment to the resistive heat generator. The power controller calculates the temperature-resistance property of the resistive heat generator based on the power and the change in the temperature that are obtained. The power controller adjusts a power duty cycle at which the power is supplied to the resistive heat generator in use of the resistive heat generator, based on the temperature-resistance property.

A conductor couples the at least one electrode with the at least one resistive heat generator. A slide layer covers the at least one resistive heat generator and the conductor. The slide layer includes a projecting portion that defines a surface of the slide layer. The projecting portion is defined by a film thickness of at least one of the conductor and the at least one resistive heat generator. The projecting portion includes an upstream projection disposed opposite a lateral end of the base in a longitudinal direction of the base and a downstream projection disposed downstream from the upstream projection in a rotation direction of an endless belt that slides over the heater.

Abstract: A fixing method is provided including the step of fixing a toner on a recording medium with a fixing device. The toner comprises a binder resin, a colorant, and a release agent, and has a release agent amount indicator of from 0.01 to 0.20. The release agent amount indicator is represented by a ratio (P2850/P828) of an intensity (P2850) at a wave number of 2,850 cm−1 to an intensity (P828) at a wave number of 828 cm−1 of the toner measured by a Fourier transform infrared spectroscopy attenuated total reflection method. The fixing device includes a fixing rotator driven to rotate by a driving source, a pressure rotator driven to rotate by rotation of the fixing rotator, a fixing belt interposed between the fixing rotator and the pressure rotator, and a heater to heat the fixing belt.

Abstract: Provided are an antenna and a combination antenna having a wide directivity in a predetermined plane direction. The antenna 100 is configured to have rims 111, 112 at left and right ends of a dielectric substrate 101 in the X direction in such a manner as to sandwich antenna elements 10. The rims 111, 112 may be metal plates or EBGs. As the rims 111, 112 are thus provided at both sides to sandwich the antenna elements 10, it is possible to reduce the width of the dielectric substrate 101 of the antenna 100 required for realizing wide coverage. As a result, it is possible to create a greater space for integration of another RF circuit and improve the space factor.
