Abstract: An image forming apparatus includes a developing module which develops a toner image on a printing medium, a fixing module which fixes the toner image onto the printing medium, and a toner neutralization module arranged on a travel path of the printing medium between the developing module and the fixing module to electrically neutralize the toner image on the printing medium.

Abstract: An electrophotographic recording medium can have a first layer of base material and a second layer formed on one or both surfaces of the first layer for fixing toner. The second layer can include a hollow pigment, an inorganic material and a binder resin. The amount of the hollow pigment can be in the range of about 10% to about 50% by weight based on the total weight of the second layer. The ratio of the white paper glossiness before and after printing on the recording medium may be greater than 1.5.

Abstract: A smell dilution unit includes: a blower fan; a duct which guides an external air introduced from the blower fan; and a deodorization unit which contains a smell masking agent and allows an odor of the smell masking agent to be mixed with the external air introduced from the blower fan. Since the deodorization unit containing the smell masking agent, which is replaceable, is installed in the duct, the smell dilution unit may dilute an unpleasant smell generated during printing.

Abstract: A security paper that is detectable by a metal detector has a predetermined brightness. The security paper has a low content of volatile organic compounds (VOC). Also, the security paper retains an improved detect-ability for a period of time that is greater than a predetermined period of time. The security paper includes a detectable layer including metal-polymer composite particles and an aqueous binder resin.

Abstract: A recording medium for thermal transfer printers includes: a base layer; a dye accepting layer applied to a surface of the base layer; and an inorganic material aid layer which is interposed between the base layer and the dye accepting layer. The inorganic material and layer contains an organic binder resin, an inorganic material having a particle diameter of 10 ?m or greater and a brightening agent. The recording medium has the inorganic material aid layer interposed between the base and the dye accepting layer, which facilitates transfer of a recording ribbon dye. As a result, stain and wrinkle free and clear image quality can be obtained and light resistance can also be improved.

Abstract: An electrophotographic recording medium is disclosed. The electrophotographic recording medium can include a base layer acting as the substrate, a undercoating layer formed on a surface of the base layer and a toner fixing layer formed on the undercoating layer. The undercoating layer may include one or more resins selected from a group consisting of an acryl resin, a polyurethane resin, a vinyl resin and a polyol resin. The electrophotographic recording medium disclosed herein may advantageously exhibit curling preventive characteristics and improved smoothness and glossiness.

Abstract: An electrophotographic recording medium includes a base and a toner fixation layer, wherein the toner fixation layer includes a filler, a binder, and a surface hardener. The electrophotographic recording medium can have superior toner fixability, high printing gloss, and high printing quality.

Abstract: A printing medium has a base layer, an ink receptive layer coated on the base layer, and an undercoating layer formed between the base layer and the ink receptive layer. The undercoating layer has a highly glossy resin property. Accordingly, regardless of a type of a material that is used in the base layer, the printing medium always offers rapid ink absorption, a vivid color image, excellent color fixation, a high water and light resistance, and high glossiness.

Abstract: A composition for forming an ink acceptable layer of a recording medium for inkjet printers and a recording medium for inkjet printers using the same. The composition comprises an inorganic filler, hydrophilic binder, core-shell structured cationic latex and polyamide-epichlorohydrin resin, and the recording medium comprises the above-described composition for forming an ink acceptable layer. The composition provides a recording medium for inkjet printers comprising an ink acceptable layer having excellent water and moisture resistance while maintaining a superior ink absorption amount and ink absorption rate.

Abstract: An ink-jet recording medium including: a substrate; and an ink receiving layer coated on a surface of the substrate and including an inorganic filler, a polyvinyl alcohol, a cationic core-shell latex with a glass transition temperature (Tg) of at least 50° C., and a zirconium compound.
