<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner sharp in particle diameter distribution and superior in fluidity and storage stability and not changed too much in chargeability even in both environments of a low temperature and a low humidity, and a high temperature and a high humidity, and restrained from deterioration of image quality even in the case of continuous printing, and further, capable of dealing with lowering of the fixing temperature and raising of the printing speed and formation of full color images, and capable of enhancing the resolution. SOLUTION: This electrostatic charge image developing toner comprises at least a binder resin and a colorant and a charge controller and this charge controller comprises a charge positively controlling resin (A) made of a polymer having a weight average molecular weight of 1,000-100,000 and functional groups giving positive chargeability, and a charge negatively controlling resin (B) having a weight average molecular weight of 1,000-100,000 and functional groups giving negative chargeability.</p> |
