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 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： 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 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： A mobile image forming apparatus includes a body, a recording device supported by the body and configured to form an image on a recording medium, a roller provided to the body and configured to rotate on the recording medium while the body is moved in a scanning direction for image formation. The mobile image forming apparatus further includes a switching device configured to switch a state of the mobile image forming apparatus during image formation between a roller contact state in which the roller is in contact with the recording medium and a roller contactless state in which the roller is contactless with the recording medium.
