TONER

摘要

The present invention provides a toner excellent in light resistance. The toner includes toner base particles, each of which contains a binder resin, a wax and a coloring agent, and a coloring matter compound represented by the general formula (1) is contained as the coloring agent.;;wherein R1 and R2 each independently represent an alkyl group or an acyl group, or R1 and R2 may be bonded to each other so as to form a cyclic organic functional group containing, as a hetero atom, a nitrogen atom to which R1 and R2 are bonded; R3 and R4 each independently represent an alkyl group; R5 and R6 each independently represent an alkyl group or an alkoxy group; R7 represents a hydrogen atom, an alkyl group or an alkoxy group; and R8 represents an alkyl group.
