Patent ID: 7532354

Claim:
A duplex transferring apparatus that transfers a first visual image from a first image carrier onto a first side of a recording medium and a second visual image from a second image carrier onto a second side of the recording medium, to transfer a visual image onto both sides of the recording medium, the duplex transferring apparatus comprising: a first-side reflected-light detector including a first light-emitting unit that emits a first light; and a first light-receiving unit that receives the first light reflected on the first side of the recording medium; a second-side reflected-light detector including a second light-emitting unit that emits a second light; and a second light-receiving unit that receives the second light reflected on the second side of the recording medium; and a transfer-condition setting unit that independently sets a first transfer condition for transferring the first visual image and a second transfer condition for transferring the second visual image, based on a result of detections by the first-side reflected-light detector and the second-side reflected-light detector, wherein the first-side reflected-light detector and the second-side reflected-light detector are arranged in such a manner that the first light-receiving unit is fixed at a position off from an extension line from the second light-emitting unit in an emitting direction of the second light-emitting unit, and the second light-receiving unit is fixed at a position off from an extension line from the first light-emitting unit in an emitting direction of the first light-emitting unit.
