PURPOSE:To obtain the cyan toner having various good characteristics, such as optical characteristics and electrostatic charge characteristics by incorporating a specific compd. into a binder resin. CONSTITUTION:The cyan toner for electrophotography having the various good characteristics including enhanced light transmittability, spectral reflecting characteristics, affinity of a dye, pigment and a binder resin, electrostatic charge characteristic, and fastness to light and heat is obted. when the compd. expressed by general formula I is incorporated into the binder resin. In the formula, R: a hydrogen atom, substd. or unsubstd. alkyl group, cycloalkyl group, allyl group or substd. or unsubstd. phenyl group; X: a cyano group or alkoxycarbonyl group. |
