<P>PROBLEM TO BE SOLVED: To provide a toner with which stable developability and a favorable output image with suppressed image fog can be obtained even in various use environments. <P>SOLUTION: The toner is to be used for a nonmagnetic single component image forming method. A toner carrier to be used is an elastic roller having an elastic layer around a core body and a surface layer formed on the circumference face of the elastic layer, wherein the surface layer of the elastic roller contains (a) at least a polyether polyurethane resin having a polypropylene glycol unit and/or a polytetramethylene glycol unit and (b) an acrylic resin. The toner comprises toner particles containing a polymer or a copolymer having a sulfonic acid group, a sulfonate group or a sulfonic acid ester group, a binder resin, a colorant and wax, and inorganic fine particles. <P>COPYRIGHT: (C)2009,JPO&INPIT |
