Abstract
Provided is a toner including a toner particle containing an amorphous resin, a colorant, a release agent, and a crystalline resin, wherein, when η0.01 represents the extensional viscosity of the toner at a Hencky strain at 90° C. of 0.01 and η0.69 represents the extensional viscosity of the toner at a Hencky strain at 90° C. of 0.69, η0.01 and η0.69 satisfy the relationships of the following formulas (1) and (2): 3.0×104 Pa≤η0.01≤2.0×105 Pa formula (1)2.0≤[η0.69/η0.01]. formula (2)
