Abstract
A non-magnetic toner is provided. The non-magnetic toner comprises a polyester resin, a release agent, and a colorant. A storage elastic modulus at 100° C. (G'(100° C.)) of the toner is from 1.0×10to 1.0×10Pa, and a storage elastic modulus at 160° C. (G′(160° C.)) of the toner is from 1.0×10to 1.0×10Pa. A ratio of loss elastic modulus to storage elastic modulus at 100° C. (tan δ(100° C.)) of the toner is greater than that at 130° C. (tan δ(130° C.)), and the tan δ(100° C.) and the tan δ(130° C.) are each within the range of from 1 to 2.
