摘要： A toner including core particles containing at least a resin and a colorant and coated with a resin coating layer is provided. The core particles are formed by flocculating and fusion-bonding at least resin microparticles and colorant microparticles dispersed in fluid dispersion, while two or more coating layers are formed over the core particles. A wax is added to at least one of the coating layer(s) but for the outermost coating layer, and the core particles. A ratio d/r between an average thickness d of the overall coating layers and a volume average particle size r of the core particles is adjusted to 0.01 to 0.6.

摘要： An electrostatic charge image developing toner includes a toner matrix particle having a core-shell structure. The toner matrix particle contains: a core particle including an amorphous resin, a colorant, a release agent, and a crystalline resin; and a shell layer coating a surface of the core particle at a coverage of 60 to 99%. The shell layer includes an amorphous resin. The amorphous resin contained in the core particle differs from the amorphous resin contained in the shell layer. The toner matrix particle has one to seven discrete shell domains determined by observation of a cross section of the toner matrix particle with an electron microscope.

摘要： A low energy consumption monochrome particle includes a core latex having a core a glass transition temperature and a weight average molecular weight. A shell encapsulates the core and includes a shell latex having a shell glass transition temperature and a weight average molecular weight. The glass transition temperature of the shell latex is higher than the glass transition temperature of the core latex. The weight average molecular weight of the shell latex is lower or higher than the weight average molecular weight of the core latex. The low energy consumption monochrome particles are suitable for high speed printing in SCD systems while decreasing minimum fusing temperature, maintaining excellent hot offset and storage, and exhibiting a matte finish.
