Patent ID: 8679718

Claim:
A toner, comprising: a mother particle including: a core including a crystalline polyester, an amorphous polyester, a colorant, and a release agent; and a shell including resin particles; and an external additive, wherein a deformation amount H1 of the toner compressed by a pressure of 0.5 mN under a temperature of 25° C. is between 0.2 and 1.5 μm, wherein a difference D between the deformation amount H1 and a deformation amount H2 of the toner compressed by a pressure of 0.5 mN under a temperature of 50° C. is between 0.0 and 1.0 μm, and wherein a surface roughness Ra of the toner melted at 90° C. is between 0.02 and 0.40 μm.
