摘要 PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge latent image development and a method for producing the toner, capable of maintaining hot offset resistance, although the toner contains a resin having a polyhydroxy carboxylic acid skeleton comprising an optically active monomer, and having excellent low temperature fixing property, giving an image with good image density and a haze degree, and having good heat-resistant storage property, and to provide a developer, an image forming apparatus, an image forming method and a process cartridge using the developer. SOLUTION: The toner for electrostatic charge latent image development contains a binder resin, a colorant and a releasing agent, wherein the binder resin comprises a polyester resin (a) having crystallinity and no polyhydroxy carboxylic acid skeleton comprising an optically active monomer and a resin (b) having the polyhydroxy carboxylic acid skeleton. The polyhydroxy carboxylic acid skeleton in the resin (b) has an optical purity X(%)=¾X(L-form)-X(D-form)¾ of not more than 80% calculated on the monomer basis. In above expression, X(L-form) and X(D-form) represent a L-form ratio (mol%) and a D-form ratio (mol%), respectively, calculated on the optically active monomer basis. COPYRIGHT: (C)2011,JPO&INPIT
