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.

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： In an image forming apparatus, an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image. A printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller to transfer the toner image onto the printing paper. The transfer roller applies different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported. An electric field weaker than the predetermined transfer electric field is applied to the leading edge. Even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor.

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： 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.
