US 4,905,047 A · Wet type image forming apparatus

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.

A wet type color image forming apparatus comprising:

a plurality of photoconductors disposed on a line in series on each of which photoconductors an electrostatic latent image of a different color is formed;
a plurality of liquid developer tanks from which a liquie developer of a different color is supplied to the corresponding photoconductors, respectively, to form a visual image thereon;
a transferring portion disposed under each of the photoconductors where the visual image is transferred to a transfer paper in such a way that the visual images of a different color formed on the photoconductors are superposed one above the other in sequence to form a multicolored image on the transfer paper;
a conveyor belt which passes through each transferring portion to interconnect the transferring portions disposed under the plurality of the photoconductors, respectively;
a plurality of cleaning units disposed corresponding to the plurality of the photoconductors, respectively, for removing the liquid developer remaining on the photoconductor after the visual image is transferred to the transfer paper;
and
a sealing plate disposed for each of the cleaning units in such a way that the sealing plate abuts against the photoconductor surface on an upstream side of a cleaning portion with respect to a direction of the movement of the photoconductor surface so as to prevent the liquid developer from dripping.
