PURPOSE:To obtain a silver color toner having excellent electrophotographical characteristics and ornamental effect by incorporating a pigment coated with a thin layer consisting of titanium dioxide on a flaky inorg. crystal substrate as a coloring agent into the toner. CONSTITUTION:This toner for electrophotography formed by incorporating a resin for fixing, coloring agent and compounding agent for the toner is the silver color toner for electrophotography of which the coloring agent is the pigment coated with the thin layer consisting of the titanium dioxide on the flaky inorg. crystal substrate. Mica is most preferable in terms of an aspect ratio as the flaky inorg. crystal substrate of the pigment and any material which is the flaky inorg. crystal is used. The amt. of the titanium dioxide to be deposited on the flaky substrate is 10-60wt% titanium oxide per the pigment. The flaky pigment has preferably 1-40mum average grain size. The metallic gloss tends to be lost if the grain size is <=1mum and the pigment of the grain size suitable for the toner is difficult to be obtd. if the grain size is >=40mum. |
