20100261110 | TONER, TONER PRODUCTION METHOD, AND IMAGE FORMING DEVICE USING THE SAME - A toner, has a number mode diameter of 3 μm or more and 6 μm or lower and a particle size distribution of a toner including an externally-applied agent in the range of 0.6 μm to 400 μm in which the number frequency of a toner smaller than the number mode diameter is smaller than the number frequency of a toner equal to or larger than the number mode diameter. | 10-14-2010 |
20100261111 | TONER, IMAGE FORMING METHOD AND IMAGE FORMING APPARATUS - A toner includes at least a binder resin, a colorant, and a release agent. The toner contains base toner particles having an average volume particle size of 2 μm to 6 μm, small particle silica having an average volume particle size of 7 nm to 15 nm, large particle silica having an average volume particle size of 50 nm to 400 nm, small particle transition alumina having an average volume particle size of 7 nm to 20 nm, and large particle α-type alumina having an average volume particle size of 50 nm to 400 nm or large particle cerium oxide having an average volume particle size of 50 nm to 400 nm. | 10-14-2010 |
20100261113 | TONER, METHOD FOR FORMING IMAGE, AND IMAGE FORMING APPARATUS - A toner includes toner base particles containing at least a binder resin, a coloring agent, and a release agent and having a volume-average particle size of 2 to 6 μm; a small particle size silica having an average particle size of 7 to 15 nm; a large particle size silica having an average particle size of 50 to 400 nm; and a small particle size transition alumina obtained by a dawsonite method and having an average particle size of 7 to 20 nm. | 10-14-2010 |
20110242196 | INK JET RECORDING METHOD - An ink jet recording method includes ejecting at least two color ink compositions onto a recording medium so as to be deposited one on another. When one ink composition is deposited to form a first image and then another ink composition is deposited to form a second image on the first image, the ink composition forming the second image has a higher yield value than the ink composition forming the first image. | 10-06-2011 |
20110242213 | INK JET RECORDING METHOD - The ink jet recording method includes performing printing by depositing droplets of an ink composition ejected from the ink ejection nozzles on a recording medium transported in the direction perpendicular to the nozzle alignment direction in such a manner that the droplets ejected from at least one ink ejection nozzle located at an end of each of ink jet heads adjacent to each other in the direction perpendicular to the nozzle alignment direction are deposited one on the other. The volume of droplet ejected from the ink ejection nozzle at the end of the ink jet head is smaller than the volume of ink droplet ejected from each of the other ink ejection nozzles of the ink jet head, and the ink composition has a yield value of 0.50 to 2.00 mPa. | 10-06-2011 |
20120262516 | INK JET RECORDING AQUEOUS PIGMENT INK - An ink jet recording aqueous pigment ink contains a self-dispersing pigment, a quaternary amino acid, a non-polymeric, nonionic material having a melting point of 40° C. or more, and at least one of trialkylamine and trialkanolamine. The content of the non-polymeric, nonionic material is 3% to 15% by mass relative to the total mass of the ink jet recording aqueous pigment ink. | 10-18-2012 |
20130241991 | INK JET RECORDING METHOD - An ink jet recording method using a recording apparatus including a plurality of ink jet heads, comprising performing printing by depositing droplets of an ink composition ejected from the ink jet heads on a recording medium, wherein the ink jet heads are aligned in a direction cross to a transporting direction of the recording medium and the ink composition has a yield value of 0.50 to 2.00 mPa. | 09-19-2013 |
20130286118 | Ink Jet Recording Method - An ink jet recording method includes ejecting at least two color ink compositions onto a recording medium so as to be deposited one on another. When one ink composition is deposited to form a first image and then another ink composition is deposited to form a second image on the first image, the ink composition forming the second image has a higher yield value than the ink composition forming the first image. | 10-31-2013 |
