    摘要： An image forming apparatus including an intake opening from which an outside air is drawn, a fixing device disposed above the intake opening to heat a recording medium to fix an image onto the recording medium, and a flow path for the air drawn from the intake opening to direct the air onto devices or components provided near the fixing device inside the image forming apparatus by negative pressure generated by an upward current of hot air generated from the fixing device.

    摘要： A heating device includes a first rotator, a heater including a base having a slide face over which an inner face of the first rotator slides, a second rotator forming an outer face nip between the first rotator and the second rotator and a slide nip between the heater and the inner face, and a lubricant holder disposed between the first rotator and the heater to hold a lubricant. The first rotator, the lubricant holder, and the lubricant satisfy a formula of H×X1×R×G≤A≤V×G, where H is a height of a roughness of the inner face, X1 is a longitudinal length of the first rotator, R is a circumference of the first rotator, G is a specific gravity of the lubricant, A is an application amount of the lubricant on the slide face or the inner face, and V is a volume of the lubricant holder.

    摘要： 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.
