1. A toner comprising toner base particles, each of which contains a binder resin, a wax and a coloring agent, wherein a coloring matter compound represented by the general formula (1) is contained as the coloring agent: wherein R1, R2 and R6 each independently represent an alkyl group, R3 to R5 each independently represent an alkyl group, or satisfy either of the following conditions i) and ii): i) R3 and R4 are bonded to each other, so as to form a cyclic organic functional group containing R3, R4 and a carbon atom bonded simultaneously to R3 and R4, and R5 represents an alkyl group; and ii) R3 to R5 are bonded to one another, so as to form a cyclic organic functional group containing R3, R4, R5 and a carbon atom bonded simultaneously to R3 to R5; and R7 and R8 each independently represent an alkyl group or an acyl group, or R7 and R8 are bonded to each other, so as to form a cyclic organic functional group containing R7, R8 and a nitrogen atom bonded simultaneously to R7 and R8.
