Abstract:
A transfer device that transfers at least one color visual image from at least one image carrier to each of first and second sides of a recording medium, comprising:a transfer element configured to hold and move the recording medium; at least one transfer bias applying device configured to apply a transfer bias to the recording medium by the transfer element in order to transfer the at least one color visual image from the at least one image carrier to the recording medium while the recording medium passes through at least one transfer nip part formed between the at least one image carrier and the at least one transfer bias applying device; and an adsorbing bias applying device configured to apply a first adsorbing bias to the first side and a second adsorbing bias to the second side of the recording medium to adsorb the recording medium to the transfer element, the adsorbing bias applying device being provided upstream of the at least one transfer bias applying device in a direction of movement of the recording medium, wherein a polarity of the second adsorbing bias applied to the second side of the recording medium is opposite to a polarity of electric charge given to the recording medium due to electric discharge generated when the recording medium is separated from the at least one image carrier after passing through the at least one transfer nip part.
