Problems solved by technology

However, because friction increases and abrasive forces increase as processing speeds increase, there is a possibility that, even if the surface has become more efficient, it will undesirably scratch the photosensitive part unless the material is carefully chosen s surface
In addition, its performance is out of the rubber state and tends to the glass state. Therefore, the scraper becomes brittle with the quality of the material, so there is a possibility that the scraper is broken and causes cleaning failure.

[0117] use figure 2 In the plasma-enhanced CVD system, a lower barrier layer and a photoconductive layer were deposited on a cylindrical aluminum substrate under the conditions shown in Table 1, and a surface layer was sequentially formed thereon under the conditions shown in Table 2. Among them, changing the flow rate of hydrogen gas and the high-frequency power supply produces five photosensitive components A-E, whose surface layers have different spin densities and spin relaxation times. The spin density and spin relaxation time values ​​of the formed films are shown in Table 6.

[0145] The five drums prepared in the above manner were mechanically rubbed against their surfaces with a certain intensity for the service life test of the copier, and thereafter, their performance after being installed in the copier and used for a long time was evaluated. First, the drum was rotated at a process speed of 400 mm / sec, and a polished SiC belt (LT-C2000, available from Fuji Photo Fim Co., Ltd.) having an average particle diameter (8 μm) was substantially equal to that of bringing the toner into contact with it. section, which then holds down a parallel pivot of 3mm diameter and 20mm width, which rubs against the drum surface under load application. Also, the polishing belt is always moved at a speed of 1mm / Sec, so as to always...

Abstract

In order to improve the release performance and slipperiness of the toner on the surface of the photosensitive member, the surface layer of the photosensitive member is formed from a non-single-crystal carbon film having a low spin density and a short spin relaxation time and including at least hydrogen atoms, thereby providing the ability to form Very precise and high-quality images with a long life, and provide a photosensitive part that has high sensitivity, does not cause any defective images due to leakage, and can be stable without any change over time Get ghost-free, high-quality images.

Description

technical field [0001] The present invention relates to a photosensitive member, a method for producing the same, an image forming apparatus having the photosensitive member, and an image forming method. In particular, the present invention relates to a photosensitive member in which an electrophotographic photosensitive member is typified in an electrostatic image forming method including electrophotography, which can obtain high-definition images under various circumstances, even if used in high-speed processing, Due to its high release characteristics, it will not cause the melting and bonding of the toner, and has sufficiently high working characteristics to maintain this characteristic, has high sensitivity, and can stably obtain high-quality images; it also relates to its preparation method, with An image forming apparatus of such a photosensitive member and an image forming method using the photosensitive member. Background technique [0002] As member materials for ...
