ABSTRACT:
In a magnetic toner having toner particles containing at least a binder resin and a magnetic material, the binder resin is chiefly composed of a resin having a polyester unit synthesized using as a catalyst a tin compound represented by the following Formula (1), and the magnetic material has a number-average particle diameter of form 0.1 μm to 0.3 μm:in-line-formulae description="In-line Formulae" end="lead"?(RCOO)2Sn Formula (1)in-line-formulae description="In-line Formulae" end="tail"?wherein R represents an alkyl group having 5 to 15 carbon atoms. This magnetic toner can attain a stable image density without dependence on environment and enables formation of high-grade images over a long period of time without causing scratches of latent image bearing members.
