ABSTRACT:
A non-spherical toner particle for developing an electrophotographic image and its producing method are disclosed. The toner particle is one which is produced by coagulating and fusing a plurality of pigment-including polymer particles which are formed by emulsion polymerization of at least one hydrophobic polymerizable monomer in an aqueous phase in the presence of a surfactant, pigment particles, which has a calcium content of zero to 0.1% by weight, dispersed in said aqueous phase and a water-soluble radical polymerization initiator.
