PURPOSE:To obtain an always stable and sharp image having no fogging by incorporating a styrene/acrylic polymer, polyalkylene having 1,000-45,000 weight average mol.wt. and photoconductive material into a titled toner. CONSTITUTION:This toner contains the styrene/acrylic polymer, polyalkylene having 1,000-45,000 weight average mol.wt. and photodonductive material. The polyalkylene is exemplified by a PE, PP, polybutylene, etc., of which the PP is more particularly effective and is generally incorporated into the toner at 1-25pts.wt., more preferably 2-10pts.wt. by 100pts.wt. resin component of the toner. Inorg. photoconductive materials such as zinc oxide, titanium oxide, cadmium sulfide, selenium sulfide, and zinc sulfide which are subjected long wavelength sensitization by a sensitizing agent such as dye or org. photoconductive materials such as copper phthalocyanine, pyro-N-vinyl carbazole, and 2, 4, 7-trinitro-9-fluorenone are applicable for the photoconductive material. |
