(b); and the toner includes: colored particles.; and external additive particles comprising a complex oxide incorporating silicon atoms and at least one of titanium atoms and aluminum atoms, and a surface existing ratio of the silicon atoms (R | 08-20-2009 |
| 20090233202 | TWO COMPONENT DEVELOPER AND IMAGE FORMING METHOD - A two component developer comprising a toner and a carrier, wherein the toner includes: colored particles; and external additive particles comprising a complex oxide incorporating silicon atoms and at least one of titanium atoms and aluminum atoms, and a surface existing ratio of the silicon atoms (R | 09-17-2009 |
| 20090233205 | TWO-COMPONENT DEVELOPER - Provided is a two-component developer with which degradation of development is inhibited even in the case of prolonged use, and thereby a high quality image exhibiting high resolution and sufficient image density can be formed for a long duration. Also disclosed is a two-component developer possessing a carrier and a toner, wherein the carrier in which magnetic material powder is dispersed in a binder resin containing a phenol formaldehyde resin has a shape coefficient SF-1 of 1.0-1.2, a shape coefficient SF-2 of 1.1-2.5 and a volume-based median particle diameter of 10-100 μm, and the toner possesses a colored particle and an external additive particle, wherein the external additive particle comprises a titanic acid compound and iron, and the iron content is 100-1,000 ppm, based on the titanic acid compound. | 09-17-2009 |
| 20090239171 | TONER - It is to provide a toner which can form an image of high image quality exhibiting high resolution wherein a final visible image exhibits high image density and high thin-line reproducibility even in long-term use. In a toner incorporating at least a colored particle containing a binder resin composed of a polyester resin and a colorant, and external additive particles, the toner has a degree of average circularity of 0.950-0.990, a volume based median diameter of 4.5-8.0 μm, a volume based particle diameter dispersibility (CV | 09-24-2009 |
| 20100330491 | ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER - Provided is an electrostatic charge image developing toner producing neither halftone image unevenness nor density drop of solid images, even though a large number of print sheets are printed at high temperature and high humidity, and subsequently printing is further carried out at high temperature and high humidity after standing for a long time. Disclosed is an electrostatic charge image developing toner containing 3-10% by weight of at least one metal fluoride selected from the group consisting of sodium fluoride, magnesium fluoride, calcium fluoride, barium fluoride and aluminum fluoride, based on a total weight of the toner. | 12-30-2010 |
| 20110014561 | TONER AND TONER MANUFACTURING METHOD - Provided are a toner and a toner manufacturing method with which high image density and a broad range of color reproduction are obtained, and with which high-quality images are also obtained. The toner is composed of toner particles that comprise a binding resin containing a polyester resin and a colorant, and contains 10-1,500 ppm of a metal element selected from titanium, germanium, and aluminum, and a cyclic phenol sulfide represented by general formula (1) selected from thiacalixarene, sulfinyl thiacalixarene and sulfonyl thiacalixarene. | 01-20-2011 |
| 20110157531 | LIQUID CRYSTAL DISPLAY UNIT AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing a liquid crystal display device with which response characteristics are able to be easily improved without using major equipment is provided. The method of manufacturing a liquid crystal display device includes steps of forming a first alignment film | 06-30-2011 |
