Abstract
A wet image forming unit for developing an electrostatic latent image formed onto a surface of a photosensitive body by a liquid developing solution containing toner particles is characterized in that a squeeze roller for squeezing of a surplus developing solution on the photosensitive body and cleaning the photosensitive body is provided and, just before stop of an image forming operation, a voltage whose polarity is opposite to a charging polarity of the toner particles is applied to the squeeze roller. The squeeze roller rotates in the direction similar to the photosensitive body upon the image forming operation. However, just before the stop of the image forming operation, the squeeze roller rotates in the direction opposite to the photosensitive body. During printing, the liquid developing solution which remains and gathers at the interval between the photosensitive belt and squeeze roller is removed by the reverse rotation of the squeeze roller not only mechanically, but also electrically.
