An electrophotographic toner and a method of preparing the same, the electrophotographic toner including a binder that includes two kinds of resin having different weight average molecular weights, a colorant, and a releasing agent.

Electrophotographic toner and method of preparing the same

A toner includes a binder including two different weight molecular weight resins, a colorant, and a releasing agent, wherein a gel permeation chromatogram (GPC) molecular weight distribution curve of the toner has a major peak (Mp) present in a range of about 1.0&#xd7;10to about 3.0&#xd7;10g/mol and a shoulder curve starting at 1.0&#xd7;10g/mol or more, and a storage modulus (G') curve of the toner with respect to temperature has T, which is a temperature at which a storage modulus value begins to decrease, in a temperature range of about 50 to about 67&#xb0; C.

Toner for developing electrostatic latent image and method of preparing the same

An electrophotographic toner and a process for preparing the same. The electrophotographic toner includes a binder, a coloring agent, and a release agent. The binder includes two resins having different weight average molecular weights.

Electrophotographic toner and process of preparing the same

A toner to develop an electrostatic charge image, a method of preparing the toner, a toner supply device employing the toner, an apparatus to form an image employing the toner, and a method of forming an image using the toner are provided. The toner includes a binder resin including a first type of binder resin having a first weight-average molecular weight and a second type of binder resin having a second weight-average molecular weight different than the first weight-average molecular weight, a colorant, and a releasing agent.
