Abstract
What is disclosed a decolorizable toner of which main components are a visible ray-near infrared ray-absorbing dye, a decolorizing agent and a resin binder, characterized in that a resin binder A containing the visible ray-near infrared ray-absorbing dye is dispersed in a resin binder B and that the decolorizing agent is blended with at least one of the resin binder A and the resin binder B, and a process for preparing the same. The visible ray-near infrared ray-decolorizable toner of the present invention can be speedily decolorized by irradiating with visible rays to near infrared rays. Also, according to the process of the present invention, it is easy to adjust its electrically charged amount by a material having electrification property, and there is obtained a visible ray-near infrared ray-decolorizable toner which is hardly faded during the kneading in the production of the toner.
