Abstract:
A toner includes a crystalline polyester resin and an amorphous polyester resin. A ratio of the storage modulus of the toner G′ (To) at a temperature To to the storage modulus of the toner G′ (To+3) at a temperature To+3 is greater than or equal to 10, in a case where the temperature To is within a range from 50° C. to 65° C.
