<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner having such superior characteristics that it can provide high grade images in electrostatic charge image developing apparatus of a wide range from low speed to high speed, contains few reverse polarity and low charge components, gives an image with little surface stain, can suppress toner scattering in the developing apparatus and gives stable images from the initial stage of development to the end. SOLUTION: In the electrostatic charge image developing toner containing a binder resin and an electrostatic charge controlling agent as essential components, the binder resin contains a vinyl copolymer and the electrostatic charge controlling agent contains a polyamine compound of formula (I) (where R<1> -R<8> are each alkyl or H and R<9> is a 2-24C alkylene which may be substituted by alkyl and/or phenyl or alkylene which may contain phenylene in the principal chain).</p> |
