Abstract:
A liquid image forming apparatus including at least a driving roller, a photoreceptor web circulating along an endless path by using a backup roller and a steering roller, an image forming portion which forms a toner image on said photoreceptor web using a liquid toner including a liquid carrier, an image drying roller which absorbs said liquid carrier remaining on said photoreceptor web while performing a rolling movement while in contact with said photoreceptor web, a heating roller which heats said image drying roller, and a transfer roller which presses said photoreceptor web against said backup roller at a predetermined pressure to transfer said toner image attached to said photoreceptor web to a printing paper, said apparatus comprising:a rotation speed detection portion provided at one side of said image drying roller which detects a rotation speed of said image drying roller;a speed comparison portion which determines whether said image drying roller is rotating at a predetermined speed by comparing the rotation speed of said image drying roller detected by said rotation speed detection portion with a predetermined range of a reference rotation speed; anda controlling portion which controls said heating roller to heat said image drying roller to a predetermined reference temperature to vaporize the liquid carrier absorbed by said image drying roller when a signal from said speed comparison portion indicates that said image drying roller does not maintain said predetermined speed.
