A wet type image forming apparatus includes a photoconductive drum, a toner supplying roller that supplies toner to the photoconductive drum, a developing solution applying roller uniformly applying the developing solution onto the toner supplying roller, a developing solution supplying roller supplying the developing solution to the developing solution applying roller, and two sidewall members respectively arranged on both sides of the pair of developing solution applying roller and the developing solution supplying roller. The two sidewall members closely contact side faces of the pair of developing solution applying roller and the developing solution supplying roller at both sides thereof, respectively. The circumferential surfaces of the developing solution applying roller and the developing solution supplying roller and the two sidewall members define a deposition space for depositing the developing solution, which is configured such that the developing solution is allowed to overflow only in the developing solution supplying roller side.

Disclosed is a scanning apparatus having a cascade scanning optical system. The scanning apparatus includes: a first laser scanning optical system for deflecting a first scanning laser beam to scan a scanning surface to generate a first scanning line during modulation of the first scanning laser beam in accordance with first given image data; a second laser scanning optical system for deflecting a second scanning laser beam to scan the scanning surface to generate a second scanning line during modulation of the second scanning laser beam in accordance with second given image data, wherein the first and second laser scanning optical systems are arranged so as to align the first scanning line with the second scanning line at a point of contact therebetween in a main scanning direction to form a single scanning line; a first laser beam detector fixed at a position to detect the first scanning laser beam before the first scanning laser beam starts generating the first scanning line; a second laser beam detector fixed at a position to detect the first scanning laser beam after the first scanning laser beam has completed generating the first scanning line; a measuring device for measuring a time interval; a determining device for determining a time-delay interval; and an adjusting device for adjusting the time at which the first scanning line starts to be generated, in accordance with the time-delay interval.

A printer includes a tractor unit for feeding continuous form paper, encoders driven in synchronization with the tractor unit, and detecting sensors for detecting the encoders to generate feed pulses at a standard interval. The printer further includes a paper top sensor for detecting a leading edge of the continuous form paper to generate paper top signal and is arranged to control the feed of the paper based on the feed pulse generated after the paper top signal. In order to adjust the printing position on the paper in case where the scanning position is misaligned due to a manufacturing error, the position of the detecting sensors is adjustable with respect to the encoders to compensate for the error. Further, the position of the paper top sensor is adjustable with respect to the tractor unit in order to keep the relationship between the feed pulse and the paper top signal unchanged regardless of the adjustment of the detecting sensors.

A fixing unit, used for fixing images on a recording sheet, includes a heat roller accommodating a heater, and a press roller movable between a retracted position and an operating position. The heat roller is rotated by a driving mechanism. A moving mechanism opens and closes a gap between the press roller and the heat roller by moving the press roller between the retracted position and the operating position. An assist gear rotates the press roller in a predetermined direction when the opening/closing mechanism moves the press roller toward the operating position.
