<P>PROBLEM TO BE SOLVED: To provide toner for electrostatic charge image development that suppresses the occurrence of image failure such as fogging so as to form images with excellent density, and prevents resin fine particles from adhering to a photoreceptor drum or a developing roller. <P>SOLUTION: Toner for electrostatic charge image development includes a toner base particle containing at least a binder resin and colorant, and a resin fine particle and silica adhered on the surface of the toner base particle. The resin fine particles covers 10% or more and less than 20% of the surface of the toner base particle, and the silica covers 20% or more and less than 40% of the surface of the toner base particle. The average primary particle diameter of the resin fine particle is preferably 30 nm or more and less than 150 nm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
