<p>PURPOSE:To provide the toner which adequately stabilizes image densities even at the time of continuous copying, does not generate the stain of copies, etc., and has excellent safety by incorporating specific compds. into the toner. CONSTITUTION:The electrostatic charge image developing toner contg. at least a resin and coloring agents contains >=1 kinds of the compds. expressed by formula I. In the formula, A<1> and A<2> respectively have a hydroxyl group and carboxyl group in the adjacent substitution positions on one piece of carbon 6-membered ring at the respective ends thereof and denote a naphthyl group or anthranyl group bonded with the alkylene group connecting A<1> and A<2> in another substitution position on the carbon 6-membered ring and these groups may have an arbitrary substituent; n denotes an integer. One piece of the carbon 6-membered ring in the formula I signifies both 6-membered rings in the case of the naphthyl group and signifies the ring exclusive of the middle ring among the three rings in the case of the anthranyl group. The content of the compds. of the formula I in the toner is 0.1 to 20wt.% per 100 pts.wt. resin.</p> |
