Abstract
A crystalline polyester having a number-average molecular weight of from 5000 to 10000, a weight-average molecular weight of from 150000 to 8000000, a maximum peak temperature of heat of fusion of from 60° to 150° C., and a ratio of a softening point to a maximum peak temperature of heat of fusion (softening point/peak temperature) of from 0.6 to 1.3. The crystalline polyester can be used as a resin binder for a toner used for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing method, and the like.
