摘要： The separating part of the separating device receives a reactive force that occurs on the outer peripheral surface of the photoreceptor drum, at the contact point where the separating part and the photoreceptor drum are in contact. The separating device controller changes the position of the rotational supporting point so as to decrease the rotational moment M of the reactive force at the rotational supporting point of the separating device, in accordance with increase of the reactive force that occurs on the outer peripheral surface of the photoreceptor drum as the separating part is worn down.

摘要： A plurality of protruding portions each having a predetermined width in a circumferential direction are respectively provided at a predetermined interval along an outer periphery of a stator, and through-holes are formed at both ends in the circumferential direction of the protruding portions. A total length of the widths, which the protruding portions respectively have, in the circumferential direction is set equal to or less than 25% of an outer circumference of the stator. With this structure and by virtue of the through-holes, a compressive stress built up in an inner periphery of the stator due to pressing forces imposed on center areas of the protruding portions can be distribute toward the outer periphery of the stator.

摘要： Cleaning performance of a cleaning pad for cleaning a charging wire is maintained so that the charging voltage of an image carrier by a charging wire is stabilized. A charging wire cleaning apparatus is provided with a cleaning pad for cleaning a charging wire which charges an image carrier, a slider which is a supporting body for supporting the cleaning pad, and a screw shaft which is a moving mechanism for reciprocating the slider in parallel to the charging wire. When the slider is at a predetermined position of the reciprocation range, the cleaning pad and the charging wire are separated, and the cleaning pad is adapted to be shifted with respect to the charging wire in this state.

摘要： A charging device includes a rotatable screw gear, a motor, a support, and a protruding member. The screw gear is positioned along length of a linear electrode. The motor rotates the screw gear in forward and reverse directions. The support holds the cleaning member mounted so as to be in contact with the electrode, and is mounted unrotatably but reciprocably between a first end and a second end of the electrode. The member extends perpendicular to the length of the electrode from the support, and has a projection for being elastically fitted into a thread groove of the screw gear along a radial direction of the screw gear. The member is configured in such a manner that a distance between a starting point of elastic deformation of the member and a contact point between the projection and a thread of the screw gear differs according to whether the support is moved forward or backward.

摘要： A charging device includes a long electrode, a cleaning member, a timing device, a drive source, a load measuring device, and a control device. The drive source moves the cleaning member in the outward direction for a first time period after the outward passage time and then reverses the cleaning member in the homeward position. The load measuring device measures driving load imposed on the drive source while the cleaning member is being moved. The control device controls motion of the drive source to turn the cleaning member from the outward direction to the homeward direction at a predetermined objective point near the second end, based on sum of driving loads imposed on the drive source while the cleaning member is being moved from the first point to a second point located along the outward direction.

摘要： In an image forming apparatus of the present invention, a scorotron charging device has a meshed grid electrode which is meshed more coarsely in a high-speed apparatus than a meshed grid electrode in a low-speed apparatus according to a circumferential velocity of a photoreceptor. With this arrangement, it is possible to charge the photoreceptor at a predetermined potential in the high-speed apparatus, without increase of the amount of ozone generation and upsizing of the image forming apparatus.

摘要： Transfer roller(s) is/are such that either end thereof is formed from fibrous electrically conductive component(s) and such that cylindrical portion(s) in central region(s) is/are, for example, formed from metal roller-like structure(s), either fibrous electrically conductive component outer end being arranged so as to extend somewhat beyond either transfer/transport belt side. Furthermore, outside diameter(s) approximated by tips of respective individual fiber(s) of fibrous electrically conductive component(s) is/are somewhat larger than diameter(s) of metal roller-like structure(s). This makes it possible for electric field(s) to be applied, and for charging to occur, along the full width(s) of transfer/transport belt(s).

摘要： A timer clocks and accumulates time periods during each of which a recording sheet is transported or transfer bias is applied as transfer execution periods. When the accumulated value reaches a predetermined value, the timer outputs a time-up signal to a CPU and then clears the accumulated value. The CPU executes a cleaning operation at the time the time-up signal is inputted from the timer. In the cleaning operation, the CPU causes a high-voltage power source to apply cleaning bias to a transfer electrode roller while causing a high-voltage power source to apply delivery bias to an auxiliary cleaning roller, in order to return toner attracted to the auxiliary cleaning roller to a photosensitive drum via a transfer belt.
