ABSTRACT:
The present invention relates to a toner for electrophotography containing a resin binder, a colorant, and a clay-organic complex obtained by intercalating into a smectite clay a quaternary ammonium salt represented by the formula (A):in-line-formulae description="In-line Formulae" end="lead"?[(R1)3(R2)N]+.X− (A)in-line-formulae description="In-line Formulae" end="tail"?wherein R1and R2are not identical; R1is an alkyl group, alkenyl group, or alkynyl group, each having 4 to 24 carbon atoms; R2is an alkyl group, alkenyl group, or alkynyl group, each having 1 to 10 carbon atoms; and X−is an anion. The toner for electrophotography of the present invention is suitably used for, for example, developing a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
