摘要:
A toner to develop an electrostatic latent image which includes a latex, a colorant, and a release agent, wherein the toner has a complex viscosity (η*) in a range of about 2.5×102 to about 1.0×103 Pa·s and a loss tangent (tan δ) in a range of about 1.3 to about 2.3 at a temperature of about 160° C. and wherein the η* is defined by a formula η*=(G′2+G″2)½/w, and the tan δ is defined by a formula G″/G′, where G′ is a storage elastic modulus and G″ is a loss elastic modulus as determined under the following conditions of an angular velocity being about 6.28 rad/s and at a temperature increasing at a rate of about 2.0° C./min.
