摘要： A transfer device (10) transfers a visual image from an image carrier (8) to a recording medium (S). The transfer device (10) includes a first transfer element (10a) that moves and receives the visual image from the image carrier (8) on a first surface of the first transfer element (10a), a second transfer element (3) provided opposite to the first surface of the first transfer element (10a) to pinch and convey the recording medium (S) through a transfer nip part formed between the first surface of the first transfer element (10a) and the second transfer element (3), and a facing member (2,12,22,32) provided on a second surface of the first transfer element (10a) opposite to the first surface of the first transfer element (10a). The facing member (2,12,22,32) faces the second transfer element (3) via the first transfer element (10a). The transfer device (10) further includes a constant-current power supply (4) that applies an electric voltage to a voltage application electrode (2a,12a,22a,32a) such that the visual image on the first surface of the first transfer element (10a) is transferred to the recording medium (S). The voltage application electrode is included in the facing member or in the second transfer element. A constant-current controller (11) controls a current which flows due to the electric voltage, to be constant.

摘要： A method and apparatus are disclosed for controlling image defects related to transfer of toner images in an electrostatographic machine. An engagement between an operational surface of a toner image bearing member and an operational surface of another member forming a transfer nip is adjusted using an engagement adjustment device (26,27) in order to reduce or eliminate image defects relating to an overdrive or underdrive associated with the nip. A transfer nip for transferring a toner image may include two rollers (11,21) supported by parallel shafts coaxial with each roller, the shafts separated by a controllable distance of separation and the engagement in the nip being controllably adjustable by an engagement adjustment device (26,27) to increase or decrease the distance of separation. The engagement adjustment device (26,27) provides a preselected amount of overdrive or underdrive between a toner image forming member and a receiver member to which a toner image is transferred, which preselected amount includes zero. An engagement adjustment device (26,27) of the subject invention may also be employed to control an overdrive or an underdrive in a fusing station of an electrostatographic machine.
