摘要： An image transfer device which transfers a charged toner carried on an image carrier onto a copying material comprises a transfer drum having a conductive base and an insulating surface, the transfer drum being arranged opposite to the image carrier. An electrical charge is applied to the copying material in advance of the copying material arriving at the insulating surface of the transfer drum. An electrical charge is also provided on the surface of the transfer drum in advance of the copying material arriving at the insulating surface of the transfer drum for attracting the copying material to the surface of the transfer drum and to maintain the attraction by the charges during a copying operation. In place of providing a specified charge on the surface of the transfer drum, a bias voltage can be applied to the conductive base of the transfer drum to provide the attraction force for improving attraction of the copying material to the surface of the transfer drum and to maintain the attraction during a copying operation.

The stress detection method includes, first and second force sensors whose detection axes are orthogonal to each other. When the detection axis of first force sensor forms angle θ with direction of detected stress Ax, and the stress component of direction perpendicular to direction of the detected stress Ax is Az, output Apx of the axis direction of first force sensor is found as Apx=αx (Ax×cos θ+Az×sin θ), and output Apz of the axis direction of the second force sensor is found as Apz=αz (Ax×sin θ+Az×cos θ), and, when αx and αz are detection sensitivity coefficients of first and second force sensors respectively, the detection sensitivity coefficient αz of second force sensor is set as αz=αx tan θ, and the detected stress Ax is found as Ax=(Apx−Apz)/αx(cos θ−tan θ×sin θ).

摘要： An ink-jet printer and a drive method for driving a recording head of an ink-jet printer are provided for controlling a size and a velocity of an ejected ink droplet. The ink-jet printer includes a droplet outlet orifice through which an ink droplet is ejected, an ink chamber communicating with the outlet orifice, an ink feed duct for feeding ink to the ink chamber, and a piezoelectric element for expanding and contracting the ink chamber in response to an applied voltage. A process for ink ejection includes a first step in which a meniscus in the outlet orifice is retracted towards the ink chamber by expanding the ink chamber, a second step in which the meniscus is moved towards the orifice by filling the chamber with ink, and a third step in which an ink droplet is ejected by contracting the ink chamber. The size and the velocity of the ink droplet ejected in the third step are controlled by controlling a position and a velocity of periodic travel of the meniscus at a start point of the third step.
