A toner including toner particles and an external additive adhering to a surface of the toner particles has the following configuration. The toner particles include a crystalline polyester resin and a wax and have an apparent viscosity at 90° C. in a range from 100000 Pa*s to 200000 Pa*s. The external additive includes a first external additive and a second external additive having an average primary particle size larger than that of the first external additive. A loose bulk density of the toner is in a range from 0.3 g/cm3 to 0.35 g/cm3. When the toner is compressed at 50° C. and 1.2 N/cm2, a compression degree of the toner is 50% or less, and a stress relaxation ratio of the toner is 27% or more.
