发明名称 TONER FOR ELECTROSTATIC LATENT IMAGE DEVELOPMENT
摘要 <P>PROBLEM TO BE SOLVED: To provide a toner having a core-shell structure that has a shell that sufficiently exhibits a function as a shell to improve durability and chargeability of the toner, and prevents adhesion of the toner to a regulating blade. <P>SOLUTION: A toner for electrostatic latent image development has a core particle having protrusions formed by resin fine particles being adhered to the surface of the core particle; and the core particle contains at least a binder resin, colorant, and a mold release agent. After a dispersion liquid of the toner is irradiated with an ultrasonic wave of 20 kHz, 80 W for five minutes, and the dispersion liquid of the toner is centrifuged, the supernatant of the dispersion liquid of the toner has the transmissivity of light of 800 nm in wavelength of 50% or more and 95% or less. <P>COPYRIGHT: (C)2013,JPO&INPIT
