摘要： An electrostatic recorder including an electrostatic latent image measuring instrument for measuring a state of an electrostatic latent image formed on a photosensitive substance, and executed a printing process until an electrostatic latent image formed on a surface of a photosensitive substance based on measured data is transferred onto a blank form as a visual image by a transfer device by adjusting control factors such as exposure, exposure time, electrostatic charge voltage, development bias, temperature and humidity. The electrostatic latent image measuring instrument is provided with distance sensors which, when a measuring electrode is disposed near to the photosensitive substance, maintains a constant distance therebetween. It is thus possible to measure an electrostatic latent image even if the photosensitive substance is eccentric. Furthermore, an arc between the measuring electrode and the photosensitive substance is prevented by utilizing a gas having a high arc starting voltage between the measuring electrode and the photosensitive substance of the electrostatic latent image measuring instrument.

摘要： A printer for printing a desired print pattern on print regions of a paper having non-print regions including a light source, a control device including a plurality of optical switch elements having opposed electrodes with a ferroelectric liquid crystal material being interposed therebetween, and a photosensitive drum to which transmission light of the optical switch elements is radiated for enabling printing the pattern on the paper. The control device applies a positive or negative voltage between the opposed electrodes of each of the plurality of optical switch element selectively during a first period so as to control the quantity of transmission light between the opposed electrodes, and effects a short-circuit by simultaneously applying a substantially zero voltage between the opposed electrodes of all of the plurality of optical switch elements during a second period so as to reduce the quantity of non-uniform existence of ions in the ferroelectric light crystal material between the opposed electrodes. The second period is a period provided before and/or after the first period and the second period being shorter than the first period with the second period corresponding to at least one of the non-print regions at leading and trailing end portions of the paper among the non-print regions of the paper.

摘要： An ink jet recording head has a plurality of ink-discharge electrodes and control electrodes and an opposed electrode arranged at a fixed spacing and grounded. A pulse voltage with a reversed polarity is applied to the control electrodes in synchronization with the superimposition of the pulse voltage on a bias voltage applied to the ink-discharge electrode when the ink is discharged. As a result, an ink jet recording apparatus, which can decrease the pulse voltage needed to discharge the ink, is provided with a simple configuration.

摘要： A parallel circuit of a capacitor and a varistor is connected between a ground and an aluminum cap of a photosensitive drum having a photoconductor sheet wound on a surface of an aluminum drum. The capacitor is charged by a charger. A developer roll connected to a bias voltage supply is provided with a retraction mechanism and is controlled so that the developer roll is separated from the drum mechanically upon start of operation of a recording apparatus until a potential of the cap is increased to a predetermined value and a developing agent layer does not come into contact with the cap. Alternatively to retraction of the developing roll, the developing roll may be stopped to control a height of bristle of developing agent or a bias voltage of the developer may be reversed.

摘要： It has been discovered that a cause of a transfer member winding on an image carrier at the time of transfer is attributable to a discharge in a gap formed between a forward end of the image carrier and a transfer member transporter and is characterized in that the discharge in that gap is ineffectuated by being controlled. An image-forming apparatus capable of preventing not only the winding on the image carrier, but also the fouling of the forward end even when the transfer member is changed in size, is provided by controlling the discharge in the gap. The gap may be ineffectuated by being pressed physically using a guide, thereby preventing the discharge in the gap. As an alternative, the transfer charge amount is controlled in accordance with the position where the forward end of the image carrier passes the transfer element.
