摘要： The electrophotographic toner for negative charging according to the present invention is characterized in that a metal compound of an aromatic hydroxycarboxylic acid is used as a charge-controlling agent for negative charging and a quaternary ammonium salt having an oxyacid anion is used as a charge-controlling assistant in combination with the charge-controlling agent. This quaternary ammonium salt used as the assistant is incompatible with a fixing resin but dispersible therein. Therefore, the toner of the present invention provides a sharp distribution of the charge quantity, and formation of a highly charged toner having no contribution to development or a lowly charged toner causing scattering of the toner can be effectively prevented.

摘要： Disclosed are a two-component type developer for use in the electrophotography or electrostatic printing, which comprises a magnetic carrier and a toner, and a process for the preparation thereof. This developer has a dynamic resistivity (Rd) lower than the dynamic resistivity (Rc) of the magnetic carrier. This developer is prepared by mixing a toner with a magnetic carrier so that the dynamic resistivity (Rd) of the formed developer is lower than the dynamic resistivity (Rc) of the magnetic carrier. This developer is capable of realizing an excellent reproducibility of a fine line image and a high density of a solid image area simultaneously.
