Cyan toner containing compound having azo skeleton

A cyan toner comprising toner particles comprising:

• a binder resin;
• a compound having a partial structure and a polymeric portion having a monomer unit, the partial structure being bound to the polymeric portion;
• and
• a phthalocyanine pigment as a colorant, wherein, the partial structure is represented by the following formula (1):
• [wherein at least one of R1, R2, and Ar is bound to the polymeric portion with a linking group or a single bond;
• R1 and R2 not bound to the polymeric portion each independently represent an alkyl group, a phenyl group, an OR5 group, or an NR6R7 group;
• Ar not bound to the polymeric portion represents an aryl group;
• R1 bound to the polymeric portion and R2 bound to the polymeric portion each independently represent a divalent group in which a hydrogen atom in the alkyl group, the phenyl group, the OR5 group, or the NR6R7 group is eliminated;
• Ar bound to the polymeric portion represents a divalent group in which a hydrogen atom in the aryl group is eliminated;
• and
• R5 to R7 each independently represent a hydrogen atom, an alkyl group, a phenyl group, or an aralkyl group;
• and the monomer unit being represented by the following formula (2):
• wherein R3 represents a hydrogen atom or an alkyl group;
• and
• R4 represents a phenyl group, a carboxyl group, a carboxylic acid ester group, or a carboxylic acid amide group].
