Title:
TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE, METHOD FOR MANUFACTURING TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE, DEVELOPER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE, TONER CARTRIDGE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2011027869
Kind Code:
A
Abstract:

To provide a toner for developing electrostatic charge images, which prevents an external additive from being buried or seceding on the surfaces of toner particles as compared with the toner for developing the electrostatic charge images not including toner particles having 5-20 atom% of an increase in crystal components of the surface due to XPS analysis before and after heating for 24 hours at 30-60°C.

The toner for developing the electrostatic charge images includes the toner particles. The toner particles include: an amorphous resin; a crystal resin compatible with the amorphous resin; a coloring agent; and a component for adjusting compatibility between the crystal resin and the amorphous resin. The toner for developing the electrostatic charge images has an increase of 5-20 atom% in surface crystal component due to X-ray photoelectron spectral (XPS) analysis before and after heating for 24 hours at 30-60°C.
