20100330484 | BLACK PARTICLES AND A MANUFACTURING METHOD OF THE SAME, A BLACK TONER USING THE SAME, AND A PARTICLE CONTAINER AND A TONER CONTAINER - Black particles include a black pigment; and a cyan pigment, wherein when the reflectance to light of wavelength of 420 nm and the reflectance to light of wavelength of 770 nm of plural samples are measured, the standard deviations (1σ) of the measured values are about 1 or less with respect to both wavelengths. | 12-30-2010 |
20120015291 | ELECTROSTATIC IMAGE DEVELOPING CARRIER, ELECTROSTATIC IMAGE DEVELOPER, IMAGE-FORMING METHOD, DEVELOPER CARTRIDGE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - An electrostatic image developing carrier includes a core particle and a coating layer on the core particle. The coating layer contains a resin having a crosslinked structure formed by using at least one compound selected from boric acid and boric acid derivatives. | 01-19-2012 |
20120040284 | ELECTROSTATIC IMAGE-DEVELOPING TONER, ELECTROSTATIC IMAGE DEVELOPER, TONER CARTRIDGE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - An electrostatic image developing toner that includes a toner particle including a binder resin containing a resin selected from an acrylic resin, a styrene-acrylic resin, and a styrene-(meth)acrylic acid ester copolymer. The resin has a crosslinked structure formed by using at least one of boric acid and boric acid derivatives. | 02-16-2012 |
20130089816 | Black Particles and a Manufacturing Method of the Same, A Black Toner Using the Same, and a Particle Container and a Toner Container - Black particles include a black pigment; and a cyan pigment, wherein when the reflectance to light of wavelength of 420 nm and the reflectance to light of wavelength of 770 nm of plural samples are measured, the standard deviations (1σ) of the measured values are about 1 or less with respect to both wavelengths. | 04-11-2013 |
20140106275 | ELECTROSTATIC-IMAGE DEVELOPING TONER, ELECTROSTATIC IMAGE DEVELOPER, TONER CARTRIDGE, PROCESS CARTRIDGE, IMAGE-FORMING APPARATUS, AND METHOD FOR FORMING IMAGE - An electrostatic-image developing toner contains an amorphous polyester resin that has repeating units having a backbone derived from dehydroabietic acid in a main chain thereof and that has a weight average molecular weight of about 30,000 to about 80,000; and at least one of a crystalline polyester resin containing a dicarboxylic acid (C10) and a diol (C9) as polymerization components and a crystalline polyester resin containing a dicarboxylic acid (C9) and a diol (C10) as polymerization components. | 04-17-2014 |
