Abstract
A toner to develop an electrostatic charge image, 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 at least a binder resin, a colorant, and a releasing agent. By using the binder resin including a combination of a reduced molar weight binder resin, an increased molar weight binder resin, and the releasing agent having an effecdtive compatibility with the binder resin together, the toner has accurately-controlled dynamic viscoelastic properties represented by a loss tangent. The toner to develop an electrostatic charge image according to an embodiment has development stability, development lifetime, fixability, charging stability, gloss, an anti-offset property, and heat storage ability at predetermined levels or higher.
