PURPOSE:To make the development and transfer faithful to a latent image possible by incorporating a binder resin, coloring agent and the metallic complex of a quinaldic acid substituent. CONSTITUTION:This toner contains at least the binder resin, coloring agent and the metallic complex of the quinaldic acid or the quinaldic acid substituent having >=1 substituents. The metallic complex is the metallic complex of Zn, Cr, Cd, Fe, Co, Cu or Ni. The metallic complex is stable with heat and time, has lower hygroscopicity and is a good-quality electric charge controlling agent to yield a developer having excellent electrophotographic characteristics when incorporated into the developer. The representative embodiment of the metallic complex is formula 1. |
