To provide a toner having both low-temperature fixability, heat-resistant storage stability and development stability. A toner having a core-shell structure comprising a core containing crystalline polyester, non-crystalline polyester, a colorant and a release agent, and a shell containing resin fine particles, and containing an external additive, the toner comprising: The deformation amount H1 when compressed at a pressure of 0.5 mN in a 25 ° C. environment is 0.2 μm or more and 1.5 μm or less, and the deformation amount H2 when compressed at a pressure of 0.5 mN in a 50 ° C. environment A toner having a difference D from the deformation amount H1 of 0.0 μm to 1.0 μm and a surface roughness Ra when the toner is melted at 90 ° C. of 0.02 μm to 0.40 μm.
