<p>PURPOSE:To eliminate the blocking phenomenon of toner on a color mixture part and to obtain an image having more excellent color mixture by specifying the glass transition point and flow temperature of color toner. CONSTITUTION:At least, either of the glass transition point and flow temperature of the color toner is set higher as the color toner has higher average light transmittance with respect to light in the visible region. For instance, the average molecular weight of resin and the mixing ratio of styrene and acrylic can be adjusted for each color, so that magenta toner, cyan toner and yellow toner are arranged in the order of a low glass transition point and flow temperature. When the toner of this conditions is used to attain a transfer and fixing on a recording medium, the cyan toner C is first melted and spread so as to intrude under the yellow toner Y and then, it is spread so as to cover, from the melting characteristic. The toner of low average light transmittance is fixed on a lower layer and the toner of high average light transmittance is fixed on an upper layer, so that the image excellent in color mixture can be obtained.</p> |
