Abstract
An achromatic apparatus achromatizing an achromatic toner image on paper by an achromatic toner containing a near-infrared ray absorbing colorant that is a cyanine-based colorant, and an organic boron-based compound includes heater units each of which are a ceramic heater arranged across an achromatic convey path of an achromatic unit, and light source units each of which include an LED array chip having a center wavelength shifted to the long-wavelength side from the peak of the first absorption band of the near-infrared ray absorbing colorant and within a predetermined wavelength range. While the paper formed with the achromatic toner image is being conveyed through the achromatic convey path at a liner speed of equal to or faster than 15 mm/sec, the achromatic toner image is heated to a predetermined temperature, and is irradiated with achromatic light from the LED, and thus achromatized efficiently at a low energy consumption.
