TONER CONTAINER, IMAGE FORMING UNIT, AND IMAGE FORMING APPARATUS
A toner container used in an image forming apparatus including an exposure unit with a light emitting diode light source. The toner container including a container body, and a cyan toner stored in the container body. The cyan toner includes a binder resin, at least one pigment, a charge control agent, and an external additive. The at least one pigment includes at least Pigment Blue. A lightness L*, a hue a*, and a hue b* of the cyan toner in a powder state satisfy: 30.04L*33.68, 1.75a*0.71, and 47.47b*45.08.
Vector pattern macro gloss
A method, a system and a recording medium for rendering a macro gloss effect using a digital front end processor and a color printer having color marking materials involve defining a vector pattern cell, and creating a pattern ink based on the vector pattern cell. The pattern ink can be constrained to write at or near an ink limit at small sizes varying from a high toner pile to a lower toner pile within a pattern ink cell based on the vector pattern cell. One or more objects and a background can be then painted with the pattern ink to create a macro gloss effect image based on the pattern ink.

Image forming apparatus
An image forming apparatus includes a toner image supporting section and a medium transfer section. The toner image supporting section includes first and second toner image supporting member that support first and second toner images at first and second linear speeds, respectively. The medium transfer section transfers, onto a medium, the first and second toner images respectively supported by the first and second toner image supporting members, to thereby cause the first and second toner images to be superimposed on each other. The following conditional expression (1) is satisfied when the medium transfer section transfers the first and second toner images onto the medium,
(Vd1Vt1)/(Vt1>(Vd2Vt2)/Vt2(1)
where Vd1 is the first linear speed, Vt1 is a first conveyance speed of the medium, Vd2 is the second linear speed, and Vt2 is a second conveyance speed of the medium.

Digital printing apparatus and processing using liquid toner
A digital printing process for xerography printing with liquid toner is disclosed, said liquid toner including a curable carrier liquid and imaging particles suspended in the carrier liquid. The process includes: forming a latent image as a pattern of electric charge on a surface of an imaging member; transferring the liquid toner onto a development member; developing the latent image by transferring liquid toner from the development member onto the imaging member in accordance with the pattern; transferring the liquid toner from the imaging member to a first substrate; applying a second substrate on the transferred liquid toner; after application of the second substrate, irradiating the liquid toner with actinic radiation or particle beams to cure the carrier liquid.
Image forming apparatus
An image forming apparatus includes a developing section, a transfer section, and a fixing section. The developing section attaches a metal-containing toner to a latent image, and attaches a non-metal-containing toner to the latent image. The transfer section transfers, onto an intermediate transfer medium, the metal-containing toner and transfers, onto a print medium, the metal-containing toner. The transfer section transfers, onto the intermediate transfer medium, the non-metal-containing toner and transfers, onto the print medium, the non-metal-containing toner. The fixing section fixes, to the print medium, the metal-containing toner, and fixes, to the print medium, the non-metal-containing toner. The fixing section causes a temperature at which the metal-containing toner is fixed to the print medium to be lower than a temperature at which the non-metal-containing toner is fixed to the print medium.
Color image forming process and color toner set
Provided is a color image forming process using colorant-containing toners of multiple colors containing colorants respectively having different resistances, wherein each of the colorant-containing toners contains an amorphous resin, a crystalline polyester resin, and a mold release agent, at least the crystalline polyester resin contained in the colorant-containing toner other than the colorant-containing toner containing a colorant having the lowest resistance contains a hybrid crystalline polyester resin formed by bonding a crystalline polyester polymerized segment and an amorphous polymerized segment, and the content of the amorphous polymerized segment in the hybrid crystalline polyester resin contained in the colorant-containing toner other than the colorant-containing toner containing a colorant having the lowest resistance is greater than the content of the amorphous polymerized segment in the crystalline polyester resin contained in the colorant-containing toner containing a colorant having the lowest resistance.
White toner for electrostatic charge image development and image forming method
A white toner for electrostatic charge image development contains a toner particle that includes a toner base particle containing a binder resin, a white colorant, and a releasing agent, and an external additive, wherein the toner particle contains, as the external additive, a fatty acid metal salt particle having a volume-based median diameter in a range of 0.5 to 1.5 m, and an average circularity of the toner particles is in a range of 0.870 to 0.950.
