<P>PROBLEM TO BE SOLVED: To provide a toner containing resin mother particles having a diameter of <4 μm and giving a high-resolution printed image with high development efficiency and less unevenness in development by means of an image forming apparatus with a line head of which the exposure spot diameter to a photoreceptor is 15-40 μm. <P>SOLUTION: The toner contains the resin mother particles and silicone oil or fluorine oil, in which the volume-average particle diameter of the resin mother particles is 2 to <4 μm, (volume-average particle diameter of the resin mother particles)/(number-average particle diameter of the resin mother particles) is >1 to <1.1, and the content of the silicone oil or fluorine oil is 0.05 to <2 mass% relative to the resin mother particles. <P>COPYRIGHT: (C)2008,JPO&INPIT |
