    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.
