The image bearer has a Martens hardness of from 185 to 250 N/m2. The toner satisfies a relation 0.13≤X/Dn≤0.16, where X [μm] represents an average value of an amount of deformation of the toner by micro-indentation at when a load reaches 3.00×10−4 N at a loading rate of 3.0×10−5 N/sec under an environment of 32 degrees C. and 40% RH, and Dn [μm] represents a number average particle diameter of the toner. The toner contains an external additive comprising silica particles and particles composed mainly of strontium titanate. The particles composed mainly of strontium titanate further contain a third element M selected from the group consisting of La, Mg, Ca, Sn, and Si.

Abstract: A binary ink developer (BID) assembly for a liquid electrophotography (LEP) printing device can include a developer roller having an electrically insulating exterior coating that receives ink from an ink supply and transfers the received ink to a photoconductive imaging cylinder in accordance with an electrostatic image on the imaging cylinder. A charge-specified boundary condition can exist at the boundary between the exterior coating and the ink. Electrically conductive ink may not be transferred to the imaging cylinder at background portions of the electrostatic image.

Abstract: A cold pressure fix toner composition includes at least one C16 to C80 crystalline organic material having a melting point in a range from about 30° C. to about 130° C. and at least one C16 to C80 amorphous organic material having a Tg of from about −30° C. to about 70° C. A method of cold pressure fix toner application includes providing the cold pressure fix toner composition, disposing the cold pressure fix toner composition on a substrate and applying pressure to the disposed composition on the substrate under cold pressure fixing conditions. The cold pressure fix toner compositions can be formed into latexes.

Abstract: A developer mix used in a dual component development (DCD) system is a mixture of toner particles and magnetic carrier particles, wherein the magnetic carrier particle is surface treated with a hydrophobized titania particle. The surface treatment with a hydrophobized titania particle may be selected from either a spherical, disk, or spindle shaped. Tribocharge of the toner and the toner charge stability across cartridge life or environments may be suitably modified by selecting a preferred size and shape of the hydrophobized titania.
