Newly developed flash color toner technology has achieved good image quality with good fixing properties as well as wide color reproduction properties. A flash fixing method demands that color toner absorbs the light energy emitted from a Xenon flash lamp. However, color toner used in the heat roller fixing method cannot absorb light energy. Therefore, flash fixing color toner uses a near-infrared absorbent. However, there is no colorless near-infrared absorbent. As a result, it is difficult to achieve good fixing and wide color reproduction. This paper studies the relationship between the amount of light energy absorbed in the color toner and fixing properties.
As a result,
Using these technologies, wide color reproduction is achieved in spite of using near-infrared additives, and simultaneously a good fixing property is obtained at a printing speed of more than 900ppm.
