Abstract

The invention relates to a toner for developing an electrostatic charge image and a manufacturing method for the toner. In the toner formed by agglutinating polymer particles, the polymer particles at least comprise fluorosiloxane modified phenylanine polymer particles A containing wax particles, and fluorosiloxane modified phenylanine polymer particles B containing colorant particles. The uniformity and the stability of charges on the granular surface of the toner are high; and the toner has the advantages of high reproducibility and high environmental resistance.

Description

technical field [0001] The present invention relates to a toner for developing an electrostatic charge image used in copiers, printers, etc., and more particularly to a toner for developing an electrostatic charge image with excellent image reproducibility and excellent environmental resistance, and a method for producing the same. Background technique [0002] Developers are classified into two-component developers (toner and carrier) and one-component developers (toner). Whether it is a two-component or a single-component, the toner is charged by friction, and the purpose of development and transfer is achieved through the repulsion and attraction between the charges. Therefore, if the surface charge of the toner particles is uneven and unstable, it may Various problems arise, including poor image reproducibility, low environmental resistance, and the like. [0003] The uniformity and stability of the surface charge of toner particles is very sensitive to relative humidit...
