PROBLEM TO BE SOLVED: To cope with high-speed printing with use of continuous paper as its recording medium and to better clean a transfer roller surface in high-speed production as well. SOLUTION: The electrophotographic printer includes a carrier liquid supply unit 11 disposed at a portion of the circumference of a transfer roller 2 between a position of image transfer onto a recording medium 7 and a transfer roller cleaning device 12 and including a carrier liquid supply roll 13 in rotational contact with a surface of the transfer roller 2 for supplying a carrier liquid onto the surface of the transfer roller 2, wherein the transfer roller cleaning device includes: a cleaning roll 17 rotating in rubbing contact with the surface of the transfer roller and having a bias voltage applied thereto which is of a polarity opposite to that of a residual toner on the surface of the transfer roller; a peripheral surface scraping blade 18 positioned downstream of the cleaning roll in the rotation direction of the transfer roller and in contact with a peripheral surface of the transfer roller; a side surface scraping blade 19 in contact with a side surface of the transfer roller, and further includes a surface scraping blade 26 disposed at a portion of the circumference of the cleaning roll and in contact with a surface of the cleaning roll.
