More Information
Summary:The present invention relates to a developing agent used for electrophotography, electrostatic recording, electrostatic printing, magnetic recording and the like, and particularly a developing agent with excellent image properties, fixing properties and storability, which is magnetic latent image developing toner. The magnetic latent image developing toner of the invention contains a permanent antistatic agent which includes quaternary ammonium base-containing copolymer, and conductive powder, and the electrical resistance of the toner is in the range of 108-1014 OMEGA x cm. The magnetic latent image developing toner also contains external additives or a charge control agent, to keep the frictional electrification of the toner to between -5 and 5 mu C/g.
