Patent ID: 6933092

Claim:
A magenta toner for electrophotography comprising a binder resin and a colorant, wherein the toner is obtained by a wet production method comprising the steps of: aggregating a dispersion of resin fine particles and colorant particles to form an aggregated particle dispersion; and coalescing the aggregated particles by heating the aggregated particle dispersion, wherein the toner contains at least a naphthol pigment having a structure represented by the following general formula (1) and a quinacridone pigment as the colorant, wherein the content ratio of the naphthol pigment to the quinacridone pigment is 80:20 to 30:70, wherein R is selected from a group consisting of the following groups, and R′ represents a hydrogen atom, an alkyl group or a methoxy group; and wherein the toner has a shape factor SF1 of 110 to 140 obtained by the equation below and a volume average particle size of 2 to 9 μm: SF 1 =R 2 /A ×π/4×100 wherein R represents the maximum length of the toner and A represents the projected area of the toner.
