ABSTRACT:
A wet type image forming apparatus which comprises: at least one rotary photoconductor drum having a surface on which an electrostatic latent image is formed; a development unit for forming a visual image from the latent image by supplying the photoconductor with a liquid developer; a transferring portion under the photoconductor drum where the developed visual image is transferred to a paper; a cleaning unit for removing the liquid developer which remains on the surface of the photoconductor after the visual image is transferred to the paper. The apparatus further comprises a drip prevention plate which is arranged to come in contact with the photoconductor surface to prevent the liquid developer from dripping through the photoconductor surface. The developer is prevented from dripping onto the transferring portion so that the paper is not stained by the dripped liquid developer.
