ABSTRACT:
A dry toner composition comprising (A) a binder resin, (B) a colorant and (C) charge control agents comprising a special metal complex of oxycarboxylic acid (C-1) and a special metal complex of azo compound (C-2) can provide high quality images without causing toner flying even after printed for a long period of time, and thus is useful for providing a dry developer and a process for forming images using said dry developer.
