Abstract: Provided is a thermoplastic resin composite material or a thermoplastic resin composite material particle that includes cellulose fibers, can be used to obtain a molded article excellent in mechanical properties such as strength, and is so excellent in fluidity during melting as to be excellent in molding processability. A thermoplastic resin composite material including cellulose fibers, a compatibilizer, and a thermoplastic resin, wherein the cellulose fibers substantially include only fibers having a fiber diameter of 1 to 50 ?m and a fiber length of 10 to 400 ?m, a composition ratio by mass of the cellulose fibers to the thermoplastic resin is 10:90 to 80:20, and arbitrary 10 sections of the thermoplastic resin composite material have a standard deviation of a proportion of an area occupied by the cellulose fibers per predetermined area, the standard deviation being 15% or less.

Abstract: [Object] To provide toner particles for developing an electrostatically charged image which are hardly affected by a particle size of resin fine particles and are more excellent in fixability and heat-resistant preservability. [Solution] A toner particle for developing an electrostatically charged image including a toner base particle and a resin coating covering the toner base particle, in which the toner base particle includes a recess on a surface of the toner base particle, the recess includes a recess having a depth of 50 nm to 500 nm, the resin coating includes a coating (A) portion having a thickness of 10 nm or more and less than 50 nm and a coating (B) portion having a thickness of 50 nm or more and 500 nm or less, and the coating (B) portion is present on the recess.

Abstract: A wax composition for toner which may give low-temperature fixability and heat storage stability to the toner and has excellent coloring agent dispersibility is provided. A wax composition for toner comprises a wax (a) containing a monoester of a straight-chain monocarboxylic acid and a straight-chain monoalcohol and an ester (b) of glycerin with mixed carboxylic acid composed of straight-chain C12 to C24 monocarboxylic acid having one hydroxyl group and straight-chain C12 to C24 monocarboxylic acid, and the wax (a) containing the monoester of straight-chain monocarboxylic acid and straight-chain monoalcohol has hydroxyl value of 30 or lower.
