Abstract
Provided are toner for developing an electrostatic latent image and a method of preparing the same. The toner has G′(60) of about 4.0×107 Pa to about 4.0×108 Pa, G′(60)/G′(80) of about 100 to about 500, and G′(100, 140) of about 3.0×103 Pa to about 1.5×105 Pa. The G′(60) and G′(80) are storage moduli Pa at about 60° C. and about 80° C. under measurement conditions of an angular velocity of about 6.28 rad/s and a heating rate of about 2.0° C./minute, respectively. The G′(100, 140) is a storage modulus Pa at a temperature of about 100° C. to about 140° C. under measurement conditions of an angular velocity of about 6.28 rad/s and a heating rate of about 2.0° C./minute.
