| 主权项 | 1. A process for producing an decolorizable electrophotographic toner, comprising: mixing an electron-donating color-developable agent with a wax having a color-developing action and having an acid value of 60 mgKOH/g or more, and heat-melting the resulting mixture, thereby allowing the electron-donating color-developable agent to develop a color; and mixing a binder resin with the mixture of the electron-donating color-developable agent in a color-developed state and the wax having a color-developing action. | ||
