<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which is excellent in environmental stability, which shows stable electrification behavior even for a long-term use or a great number of prints, which has little fog, high resolution and high gradation property and which can form a printed image free from the change in image density, and to provide an electrostatic charge image developing toner having a high transfer rate from a photoreceptor to a printing material such as paper during developing. SOLUTION: The toner manufactured by dispersing a mixture containing at least a polyester resin and a coloring agent in an aqueous medium to form fine particles of the mixture and then aggregating the fine particles, is characterized in that its surface is treated with a silicone oil.</p> |
