摘要： An objective is to provide a toner capable of obtaining clear prints with no image unevenness at low cost. Disclosed is an electrostatic charge image developing toner comprising toner particles each containing at least a binder resin, a colorant and wax, wherein a ratio {(S1/S)×100} of total area (S1) of peaks detected in a range of 36-42 ppm to total area (S) of peaks detected in a range of 0-50 ppm, in a spectrum obtained via measurement of the wax employing a 13C-NMR (nuclear magnetic resonance) measuring apparatus, satisfies the following inequality. 0.03≦(S1/S)×100≦0.50.

摘要： Disclosed is a toner for electrostatic linage development that has sufficient low-temperature fixability, can provide high post-fixing separability, and can be used for stable formation of images at high speed.The toner for electrostatic image development includes toner particles containing a binder resin. The binder resin contains as a part thereof a block copolymer having an A-B-A block copolymer structure including polymer blocks A composed of a structural unit derived from an alkyl methacrylate and a polymer block B composed of a structural unit derived from an alkyl acrylate. The glass transition point (TgA) of a homopolymer of the alkyl methacrylate forming the polymer blocks A is higher than the glass transition point (TgB) of a homopolymer of the alkyl acrylate forming the polymer block B.

摘要： Disclosed is a toner for electrostatic image development that has low-temperature fixability and hot offset resistance and also has document offset resistance. The toner contains a hyperbranched polymer which is a homopolymer formed using an inimer having, in its molecule, a polymerizable functional group and a polymerization initiating group or is a copolymer formed using the inimer and a vinyl-based monomer. The hyperbranched polymer is preferably a terminal-modified hyperbranched polymer and is preferably obtained by a living radical polymerization process.

摘要： Provided is an electrostatic charge image developing toner producing neither halftone image unevenness nor density drop of solid images, even though a large number of print sheets are printed at high temperature and high humidity, and subsequently printing is further carried out at high temperature and high humidity after standing for a long time. Disclosed is an electrostatic charge image developing toner containing 3-10% by weight of at least one metal fluoride selected from the group consisting of sodium fluoride, magnesium fluoride, calcium fluoride, barium fluoride and aluminum fluoride, based on a total weight of the toner.
