PROBLEM TO BE SOLVED: To provide an image forming apparatus which does not cause cleaning failure even when a low melting toner is used, by specifying a range of the surface free energy of an electrophotographic photoreceptor surface. SOLUTION: The photoreceptor 2 which is installed in the image forming apparatus 1 and on which an electrostatic latent image is formed by exposure to light according to image information has the surface free energy (γ) specified to 20 to 35 mN/m. The toner included in a developer 50 housed in a developing device 29 to develop an electrostatic latent image to form a toner image is specified to have 20 to 60°C glass transition temperature (Tg). By specifyingγof the photoreceptor 2 to a preferable range responding to the decrease in Tg of the toner, excessive adhesion strength of the toner to the surface of the photoreceptor 2 can be suppressed although the toner softens at low temperature. Therefore, both of improvement in the cleaning property and formation of a high-quality image can be achieved. COPYRIGHT: (C)2005,JPO&NCIPI |
