Patent ID: 8916318

Claim:
A black toner, comprising toner particles, each of which contains a binder resin, a compound and a carbon black, the compound has a structure of which a polymer portion having a monomer unit represented by the Formula (2) is bound to a structure represented by Formula (1); wherein, in Formula (1), at least one of R 2 , R 3 , Ar 1 , and Ar 2 is bound to the polymer portion directly or through a linking group, wherein each R 1 independently represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a trifluoromethyl group, a cyano group, or a hydroxyl group, R 2 and R 3 not bound to the polymer portion independently represent a monovalent group selected from the group consisting of an alkyl group, a phenyl group, an OR 4 group, and an NR 5 R 6 group and R 4 to R 6 independently represent a hydrogen atom, an alkyl group, a phenyl group, or an aralkyl group, Ar 1 and Ar 2 not bound to the polymer portion independently represent an aryl group, wherein any one of R 2 and R 3 , Ar 1 , and Ar 2 bound to the polymer portion independently represents a divalent group of which a hydrogen atom is removed from the corresponding monovalent group of any one of R 2 and R 3 , any one of Ar 1 and Ar 2 bound to the polymer portion independently represents a divalent group of which a hydrogen atom is removed from the corresponding aryl group of any one of Ar 1 and Ar 2 , m represents an integer of 3 or 4, n represents an integer of 1 or 2, and n+m is 5; and in Formula (2), R 7 represents a hydrogen atom or an alkyl group, and R 8 represents a phenyl group, a carboxyl group, a carboxylic acid ester group, or a carboxylic acid amide group.
