摘要： Flanges are pressed into opposite ends of a photoreceptor drum. A noncontact charging roller is arranged so as to face, but have no direct contact with, the photoreceptor drum. On both end portions of the noncontact charging roller, spacers are provided for maintaing a gap between the photoreceptor drum and the noncontact charging roller. The spacers are of tape form and wound around the noncontact charging roller. Winding positions of the spacers are distant by more than an effective projection length of each of the flanges from respective opposite ends of the charging roller.

摘要： The present removing system has a feature to remove a left-over toner that is accumulated on a brush that touches a left-over toner on a photoreceptor. More specifically, the present removing system is so arranged that an alternating voltage (superimposing voltage) on which a positive direct current voltage is superimposed is applied onto a conductive brush in accordance with a user's instruction. With this arrangement, even if a positively electrified left-over toner is accumulated on the conductive brush, it is possible to remove the positively electrified left-over toner accumulated on the conductive brush, because a voltage value (positive) applied on the conductive brush in a moment is large. Moreover, because a voltage of the conductive brush becomes negative in a moment, it is possible to remove a negatively electrified left-over toner attached on the conductive brush.

摘要： An isolating wall is provided for isolating, from a space outside the isolation wall, a space including: a photosensitive drum; a developing unit; a charging device; a transfer device; and a fixing device. With this configuration, the space in which powder toner (toner which is not fixed on a recording material by the fixing device) is present is isolated from the space outside the isolation wall. Thus, in an image forming apparatus using powder developer, this configuration makes it possible to (i) prevent the floating toner from going out of the image forming apparatus, or (ii) prevent the floating toner from deteriorating a function of the image forming apparatus.

摘要： The invention provides a developing apparatus, an image forming apparatus and a toner replenishing method that can restrain deterioration of toner and can stably form high quality image. Replenishing bias voltage is applied to a developing roller and a replenishing roller to charge conductive toner kept on a surface of the replenishing roller to a predetermined amount of charge. By electric field generated between the developing roller and the replenishing roller on the basis of the applied replenishing bias voltage, charged conductive toner is made fly and replenished from the replenishing roller to the developing roller. An appropriate amount of conductive toner is kept in a toner transporting body formed on a surface of the developing roller and is supplied to a photoconductor roller.

摘要： The object of the invention is to reduce the number of parts which are required for supporting a photosensitive drum in a photosensitive drum cartridge. Engaging bodies of supporting members are inserted through mounting holes of a cartridge main body. Supporting shafts are inserted into supporting shaft insertion holes formed on the sides of a photosensitive drum. When the supporting members are rotated, the side walls of the cartridge main body are fitted into gaps between flat plates and engaging pieces. The supporting members are positioned with respect to and fixed to the cartridge main body, whereby the photosensitive drum is supported in the cartridge main body.

摘要： An image forming apparatus includes a transfer drum which attracts and holds a transfer paper electrostatically. A toner image formed on a photosensitive drum is transferred onto the transfer paper when the transfer paper is wound around the transfer drum and brought into contact with the photosensitive drum. A variable voltage is applied to a conductive layer provided on an inner side of the transfer drum so as to either transfer the image onto the transfer paper or attract the transfer paper to the transfer roller. The transfer voltage is lower than the attracting voltage. The voltage applied to the transfer drum for both transfer and attraction will be variable depending on a detected humidity or type of transfer paper. In addition, a manual adjusting device is capable of adjusting the transfer or attraction voltage. A grounded conductive electrode roller is pressed against a dielectric layer provided on an outer side of the transfer drum for providing potential difference between the conductive layer and the transfer paper.
摘要翻译：图像形成装置包括静电吸引和保持转印纸的转印鼓。当转印纸缠绕在转印鼓上并与感光鼓接触时，在感光鼓上形成的调色剂图像转印到转印纸上。将可变电压施加到设置在转印鼓的内侧上的导电层，以将图像转印到转印纸上或将转印纸吸引到转印辊上。转印电压低于吸引电压。施加到转印鼓上的转印和吸引的电压将根据检测到的湿度或转印纸的类型而变化。此外，手动调节装置能够调节传送或吸引电压。将接地的导电电极辊压在设置在转印鼓的外侧上的介电层上，以提供导电层和转印纸之间的电位差。
