摘要:
A method of preparing a toner includes: preparing high molecular weight latex particles by polymerizing 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, a colorant and wax; aggregating the high molecular latex particles in the absence of an emulsifier, a colorant, and wax; and separating and drying the aggregated high molecular weight latex particles. A toner is prepared using the method described above. An image forming method using the toner and an image forming apparatus employing the toner are also provided. Using the method described above, polymerizable toner particles can be prepared using a simplified process and the colorant and was inside the toner can be easily dispersed.

In addition, the method minimizes a cleaning process, thereby decreasing the amounts of polluted water and waste water, which is very advantageous environmentally.
摘要:
A toner including a plurality of fine particles includes a core including first latex particles, a wax and a pigment, or a first latex particle-wax complex and a pigment, and a first shell layer including second latex particles and covering at least a portion of the surface of the core, a method of preparing the toner, a method of forming images using the toner, and an image forming device including a toner transferring unit. The toner can have improved fixing and charging properties, preserving properties at a high temperature and high humidity, glossness and anti-offset properties by reducing a domain size of a wax dispersed in the toner and improving dispersibility of the wax.

A toner includes a core containing a binder resin, wax, and a colorant, and an external additive layer coating the core, wherein the core is prepared such that it is extruded and extended to have a fiber phase, and is pulverized. The toner has an improved fixing ability to allow an electrostatic image to be fixed at a low temperature while having an excellent durability and an improved storage stability, while exhibiting reduced toner blocking and offset phenomena.

A hybrid toner includes micro cylinders, cores inserted into the micro cylinders, and an external addition layer covering the micro cylinders to which the cores are inserted. The hybrid toner prevents a toner blocking phenomenon, image contamination, and low storage stability which occur due to dispersion of wax and colorants to an outer surface of the toner.

摘要:
A composition for an overcoat layer suitable for use in an organophotoreceptor for liquid toner, an organophotoreceptor manufactured by employing the composition and an electrophotographic imaging apparatus containing the organophotoreceptor. Since the organophotoreceptor can maintain higher charge potential and low residual or discharge potential, the lifetime of the organophotoreceptor can be extended. Also, since the organophotoreceptor has good solvent resistance and abrasion resistance, it can be advantageously used for liquid toner.
