    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.

    摘要: A method of preparing a toner includes: preparing a toner composition including a macromonomer having a hydrophilic group, a hydrophobic group and at least one reactive functional group, at least one polymerizable monomer, and a colorant; emulsion-polymerizing the toner composition in a medium; and separating and drying the polymerized toner. A toner is prepared using the method. An image forming method using the toner, and an image forming apparatus using the toner are also provided. According to the method, the size, distribution and configuration of toner particles are easily controlled. In addition, the method does not involve the use of or minimizes the use of a surfactant, and decreases polluted water and waste water, which is very advantageous environmentally.
