<p>PROBLEM TO BE SOLVED: To reduce the amount of charge on toner in order to eliminate disadvantages, such as low image density, of highly charged toner, and to obtain sufficient charge control effect by adding only a small amount of magnetite.SOLUTION: Toner for electrostatic latent image development contains a colored resin particle prepared from a styrene-acrylic resin, a colorant, a charge control agent, a mold release agent, and surface-untreated magnetite, and the magnetite to be externally added to the particle.</p> |
