An area ratio of a peak originated from C═O stretching of the amide bond to a peak originated from C═O stretching of the ester bond is at least 0.00010 and no greater than 0.02000 in a FT-IR spectrum of the toner obtained by Fourier transform infrared spectroscopy analysis. The toner has a storage elastic modulus at 80° C. of at least 3.5×104 Pa and no greater than 5.0×104 Pa. The toner has a storage elastic modulus at 120° C. of at least 1.0×103 Pa and no greater than 10×104 Pa.

摘要： Composite materials such as composite particles have a solid non-elastomeric continuous phase made of an organic polymer having a glass transition temperature of at least 25° C. Dispersed within this solid non-elastomeric continuous phase are many multi-compartment porous chemically crosslinked elastomeric particles that have a mode particle size of at least 1 μm and up to and including 10 μm. The composite particles can be used as toner particles in electrophotographic imaging methods to provide fused toner images and especially stacked fused toner images.
