摘要： A composition forms an overcoat layer for an organic photoreceptor by combining an organic silane compound, an acrylic polymer, polyvinyl butyral and a solvent. The organic photoreceptor has increased electrical and mechanical properties, leading to improved life characteristics. Also, unlike when a single material of either acrylic polymer or silsesquioxane is used in forming an overcoat layer, when the composition of the present invention is used, it is not necessary to coat a primer or an adhesive layer, thereby simplifying a coating process and reducing the cost required in forming additive layers.

摘要： A preparation method of a toner having a micro diameter includes: blending a monomer and a dispersing agent in distilled water to prepare a monomer dispersion; polymerizing the monomer dispersion by adding a first polymerization initiator to about 1% by volume to about 50% by volume of the monomer, to cause a first polymerization; mixing the remaining monomer dispersion with the polymerized solution; and polymerizing the mixed solution by adding a wax emulsion and a second polymerization initiator, to cause a second polymerization. The present invention may be advantageously used for obtaining spherical, uniformly micro sized toner particles through the emulsion polymerization only, without performing the aggregation or melting process.
