摘要： A photoreceptor cartridge unit (K, K′) having a cartridge frame (6) made of plastic on which a photoreceptor drum (1) acting as a rotary member and its peripheral components (2, 3) are integrally mounted. The cartridge frame (6) is formed with a plurality of bearing portions (23-28) for supporting the rotary member (1) and a plurality of positioning projections (40-43) and is split, at the bearing portions (23-28), into two frame portions (6a, 6b) provided with an engageable portion (60a) and a receiver portion (60b), respectively. The peripheral components (2, 3) are formed with a plurality of positioning holes (44-47) so as to be mounted on the cartridge frame (6) through engagement of the positioning projections (40-43) with the positioning holes (44-47). The two frame portions (6a, 6b) are coupled with each other through engagement of the engageable portion (60a) with the receiver portion (60b).

摘要： An image forming apparatus includes a photoreceptor drum (15) on which a toner image is formed, a transfer drum (11) for transferring the toner image to paper by bringing the paper into contact with the photoreceptor drum (15), the transfer drum (11) having a dielectric layer (28), a semi-conductive layer (27) and a conductive layer (26) laminated in this order from the paper side, a power source which is connected to the conductive layer so as to apply a predetermined voltage to the conductive layer (26), and a conductive roller (12) for pressing the paper against a surface of the dielectric layer (28) so as to produce a potential difference between the conductive layer (26) and the paper (P). The potential difference induces charges of the same polarity as the voltage applied to the conductive layer on the surface of the dielectric layer, and charges of the opposite polarity on a back surface of the paper pressed against the surface of the dielectric layer. Thus, the paper electrostatically adheres to the transfer drum (11) in a satisfactory manner. Moreover, unlike charging by atmospheric discharge, since the surface potential of the transfer drum is stable, it is possible to prevent unsatisfactory transfers and improve the image quality.
摘要翻译：一种图像形成设备包括：感光鼓（15），其上形成有调色剂图像;转印鼓（11），用于通过使纸与感光鼓（15）接触而将调色剂图像转印到纸上;转印鼓（11） 11），其具有从纸侧依次层压的电介质层（28），半导体层（27）和导电层（26）;电源，其连接到导电层以便施加预定的电压施加到导电层（26）上;以及导电辊（12），用于将纸压靠在介电层（28）的表面上，从而在导电层（26）和纸（P）之间产生电位差，。电位差引起与施加到电介质层表面上的导电层的电压相同极性的电荷，并且在压靠电介质层表面的纸的背表面上产生相反极性的电荷。因此，纸以令人满意的方式静电粘附到转印鼓（11）。而且，与大气放电的充电不同，由于转印鼓的表面电势稳定，所以可以防止不令人满意的转印并提高图像质量。
