<P>PROBLEM TO BE SOLVED: To provide a toner that is characterized in energy-saving, low cost, and long life in consideration of preserving global environment as an ultimate objective, in particular, a toner for electrostatic charge image development that contains a resin component that can be replaced with a non-petroleum-based compound for each color, provides sufficient image density even at low-development potential and low-transfer potential during printing, requires less amount of the toner, is less likely to be scraped off, prevents the occurrence of ground fogging in printed images, and experiences less change in the charge amount for a long period. <P>SOLUTION: A toner for electrostatic charge image development contains at least a binder resin, an anti-static composition, and a positively-charged charge control agent, uses a polyhydroxyalkanoate produced by microorganisms as the anti-static composition, and contains 5 to 70 mass% of the anti-static composition. <P>COPYRIGHT: (C)2013,JPO&INPIT |
