20090017232 | MAGNETIC LATENT IMAGE HOLDING BODY, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - The present invention provides a magnetic latent image holding body in which the surface thereof has water repellency and a magnetic latent image is visualized by a liquid developer that contains a magnetic toner and an aqueous medium. | 01-15-2009 |
20090245874 | IMAGE FORMING DEVICE AND PROCESS CARTRIDGE - An image forming device contains: a latent image holding member; a latent image forming unit; a developer storage unit that stores a liquid developer including a toner and an aqueous medium; a developer supply member that supplies the liquid developer to a latent image holding member; and a transfer unit that transfers a toner image to a recording medium. The developer supply member has a surface formed of a liquid absorbent member and is disposed such that a part of the liquid absorbent member is immersed in the liquid developer stored in the liquid developer storage unit and that another part of the liquid absorbent member is in contact with and compressed by the latent image holding member. The water repellency of the surface of the latent image holding member is higher than the water repellency of the surface of the developer supply member. | 10-01-2009 |
20090262164 | DEVELOPER SUPPLY DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A developer supply device, includes: a developer holder; and a developer reservoir which is disposed inside of the developer holder, holds a liquid developer, and has at least one supply section that supplies the liquid developer from the developer reservoir to the developer holder, the liquid developer including a toner and an aqueous medium, and the developer supply device supplying the liquid developer that has been supplied to the developer holder to a medium which is a supply target for the liquid developer. | 10-22-2009 |
20090274973 | LIQUID DEVELOPER, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A liquid developer includes: an aqueous medium; and a magnetic toner which is substantially dispersed in the aqueous medium and includes a polymer compound and a magnetic powder, the amount of the magnetic powder being from about 0.2 volume % to about 5 volume % with respect to the magnetic toner. | 11-05-2009 |
20140242512 | LIQUID DEVELOPER, IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, LIQUID DEVELOPER CARTRIDGE, AND PROCESS CARTRIDGE - There is provided a liquid developer containing a toner that has a ratio G′ (65)/G′(90) of a storage modulus G′ (65) at 65° C. to a storage modulus G′ (90) at 90° C. of from 1×10 | 08-28-2014 |
20140242513 | LIQUID DEVELOPER, IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, LIQUID DEVELOPER CARTRIDGE, AND PROCESS CARTRIDGE - There is provided a liquid developer containing a toner that has a ratio G′(65)/G′(90) of a storage modulus G′(65) at 65° C. to a storage modulus G′(90) at 90° C. of from 1×10 to 1×10 | 08-28-2014 |
20140287356 | LIQUID DEVELOPER, IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, LIQUID DEVELOPER CARTRIDGE, AND PROCESS CARTRIDGE - A liquid developer includes a toner that contains a binder resin and a release agent, and a carrier liquid that has a difference (ΔSP (tc)) in SP value from the binder resin of from 1.5 to 7.0, wherein the release agent is not eluted in the carrier liquid at a temperature lower than a glass transition temperature of the binder resin. | 09-25-2014 |
20140295343 | LIQUID DEVELOPER, METHOD FOR CONTROLLING CHARGING PROPERTIES OF TONER, IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, PROCESS CARTRIDGE, AND LIQUID DEVELOPER CARTRIDGE - A liquid developer includes a toner in which a compound having a charge-accepting functional group has been bonded to a surface of toner particles, and a carrier liquid which makes a charge density of a surface of the toner become 1 μC/m | 10-02-2014 |
