Abstract: Disclosed is a toner particle having at least binder and colorant. The colorant is a dye complex comprising a dye, a nonionic surfactant and a complexing agent. The toner having this colorant exhibits improved color gamut.

Abstract: An electrostatic charge image developing toner comprises core particles formed by flocculating and fusion-bonding at least polyester resin particles containing wax and colorant particles, and a coating layer containing a resin formed over the core particles.

Abstract: An electrostatic image developing toner comprising a binder resin and a colorant, wherein the toner comprises a compound represented by the following Formula (1): wherein, R1, R2, R3 and R4 each independently represent an alkyl group having 10 to 30 carbon atoms and the alkyl group may have a substituent.

Abstract: Provided are a silane-phenol compound, a crosslinked siloxane outmost protective layer thereof, and an electrophotographic imaging member such as photoreceptor. The silane-phenol compound comprises (i) a phenol group and (ii) a silane group selected from the group consisting of alkoxysilyl, arylalkoxysilyl, aryloxysilyl, alkylaryloxysilyl, and combination thereof. The crosslinked siloxane outmost protective layer comprises the product of hydrolysis and condensation of a silanized hole transport compound and the silane-phenol compound. The crosslinked protective outmost layer may be used to manufacture an electrophotographic imaging member such as photoreceptor with improved properties such as image quality and cleanability, etc.

Abstract: An imaging member comprising a supporting substrate; a single layer photoreceptor for both charge generation and charge transport disposed on the supporting substrate, the single layer photoreceptor comprising a binder containing a polyhedral oligomeric silsesquioxane; a cross-linking agent; a charge component; an electron transport component; and a charge generating component.

Abstract: A process for preparing a latex includes polymerizing at least one monomer in the presence of an initiator to form a polymer emulsion; and adding an odor-scavenging bismuth compound to the formed polymer emulsion.

Abstract: Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material having the formula where Y1 and Y2 comprise, independently, an aromatic group; X1 and X2 are each a linking group; W1 and W2 are each a —(CH2)n— group or a —(CH2)n-1—C(?O)— group, where n is an integer between 1 and 10; Ar1 and Ar2 comprise each a divalent aromatic group; Q1 and Q2 are each O, S, or NR; Z1 and Z2 comprise, independently, a bond, a vinyl group, a —CR1?N—NR2— group, or a —CR3?N—N?CR4— group; and R, R1, R2, R3, and R4 comprise, independently, H, an alkyl group, an alkenyl group, an alkynyl group, an acyl group, a heterocyclic group, or an aromatic group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.

Abstract: A method for preparing a functional particulate organic material, including providing a suspension of a particulate organic material having an acid group on a surface thereof; reacting a metal cation with tri- or more-valence with the acid group; and reacting at least one of an organic acid and an organic acid salt with the metal cation.
