    摘要： An object of the invention is to provide an image forming apparatus being excellent in cleaning property for an electrophotographic photoreceptor and capable of forming a high-quality, high-resolution image. A surface free energy (γ) of a photoreceptor (2) which is provided in the image forming apparatus (1) and is exposed to a light corresponding to image information for formation of an electrostatic latent image is set to 20 to 35 mN/m. A volume average diameter of a toner particles included in a developer stored in a developing unit (29) to develop an electrostatic latent image and form a toner image is set to 4-7 mum. When γ of the photoreceptor (2) is set to within a small range as the particle size of toner is reduced, even small-particle-size toner hence increased in specific surface area and largely affected by a inter-molecular force is limited in adhesion force to the surface of the photoreceptor (2) to provide a good cleaning property, whereby a cleaning property is enhanced and at the same time a high-quality image can be formed.

    摘要： In an electrophotographic photoreceptor including a conductive substrate and a photoreceptive layer formed on the conductive substrate wherein the photoreceptive layer charged uniformly is exposed to light corresponding to an image information to form an electrostatic latent image, the surface free energy (γ) is determined to be at least 20 mN/m and at most 35 mN/m. The determination of γ on the surface of the photoreceptor 1 in the appropriate range makes it possible to suppress excessive adhesion of a toner to the surface of the photoreceptor, to suppress adhesion of foreign matters such as a paper powder and to make easy the separation thereof from the surface, which results in improving the cleanability of the photoreceptor. Since the image is formed with the photoreceptor 1 having always the clean surface, the damage or the decrease in image quality does not occur over a long period of time.

    摘要： A vibration insulating member fitting method includes the steps of: positioning and wrapping a sheet-like vibration insulating member 2 around a shaft 3 having an air suction/exhaust portion 5; holding the sheet-like vibration insulating member 2 onto the shaft 3 by air suction; and inserting the shaft 3 that sucks the sheet-like vibration insulating member 2 by the air suction into a hollow cylinder 13 of a photosensitive drum 1 to stop the air suction, causing the sheet-like vibration insulating member 2 to be tightly fitted onto the inner wall surface of the photosensitive drum 1 by a restoring force of the sheet-like vibration insulating member 2. A vibration insulating member recovering method includes the steps of: inserting a shaft 3 having an air suction portion into a sheet-like vibration insulating member 2 fitted on an inner wall surface of a hollow cylinder 13 of a photosensitive drum 1; starting air suction to suck and hold the sheet-like vibration insulating member 2 onto the shaft 3; detaching the sheet-like vibration insulating member 2 from the inner wall surface of the hollow cylinder 13 of the photosensitive drum 1; and taking the shaft 3 out of the hollow cylinder 13 of the photosensitive drum 1, with the sheet-like vibration insulating member 2 being sucked and held on the shaft 3.

    摘要： An information recording medium comprises a recording layer including a mixture of organic polysilane and oxo metallic phthalocyanine pigment. Information is recorded by adding heat or light to the recording layer. In a method for recording information onto the information recording medium, a decoloring reaction of oxo metallic phthalocyanine pigment is used which is caused by heating the recording layer to a temperature equal to or higher than a pyrolyzing point of organic polysilane.
