    摘要: An image forming apparatus has a driven image forming part for forming an image. A data supply device has at least one moving portion for supplying data to the image forming apparatus. For example, it may be a hard disk device or a toner sensor having an oscillator, both of which generate noise. A controller actuates the data supply device only during operation of the image forming part, and so the noise is not bothersome to the user.

    摘要: A control method for an image recorder of the type transporting a recording medium substantially vertically from a lower portion to an upper portion inside the recorder. This type of recorder transfers a toner image from a photoconductive element to the medium, and has a toner density sensor for sensing the toner density of a reference density pattern. When the medium jams in the transport path while being transported in the vertical direction, whether it has slipped out of the transported path and dropped to a position where the toner density sensor is located is determined, the sensor is turned on when the operator starts on an operation for removing the medium and when the operator ends such an operation. When the resultant two consecutive outputs from the sensor are different from each other, it is determined that the medium has dropped and the jam is in the vicinity of the sensor.

    摘要: A drive device includes a first shaft, a second shaft disposed at a position deviated from a shaft line of the first shaft, a drive source that drives the first shaft to rotate, and a drive force transmitting unit connecting the first shaft to the second shaft via the drive force transmitting unit to transmit a drive force of the drive source from the first shaft to the second shaft. The drive force transmitting unit includes a reverse preventing mechanism that prevents the first shaft from being rotated in a reverse direction. The reverse preventing mechanism includes a one-way clutch, and the drive force transmitting unit further includes a reduction mechanism that reduces a rotational speed of the one-way clutch to be lower than a rotational speed of the first shaft.

    摘要: A device for driving a charge roller, charge belt, image transfer roller, image transfer belt or similar contact type charging member used to charge an image carrier of an image forming apparatus in contact with the image carrier. The charging member is driven by an exclusive motor independent of a motor for driving the image carrier. A drive gear and a driven gear are formed of metal and resin, respectively. A flywheel is mounted on a drive roller for causing the charging member to rotate. The drive side has greater rotation energy than the driven roller side. A flywheel is also mounted on the drive gear.

    摘要: A toner supply device loaded with a removable toner cartridge for supplying a toner to a developing unit of an electrophotographic image forming apparatus. When the toner is fed from the toner cartridge to the toner supply device, an agitating member incorporated in the toner supply device is operated for a predetermined period of time to agitate the toner. The device supplies the toner evenly and rapidly to the developing unit after crushing hard masses of the toner or removing local concentration of the toner which are apt to occur in the cartridge.
