PROBLEM TO BE SOLVED: To provide a wet type electrophotographic device which is improved in the transfer efficiency by supplying cooled liquid toner to a photosensitive drum and cooling the same to a temperature lower than the temperature of an intermediate transferring roller. SOLUTION: This wet type electrophotographic device is provided with the photosensitive drum 1, scolotron electrifiers 2 which are separated from the photosensitive drum 1 and disposed at every respective colors Y, M, C and Bk, a laser beam exposure source 3 which irradiates an electrified region with an exposure beam uniformly and a developing means 4 which supplies the liquid toner which comprises toner particles and carrier solvent in which the particles are dispersed to the photosensitive drum 1. Further, this wet type electrophotographic device consists of the intermediate transferring roller 5 which is internally provided with a heater and is pressurized contact with the photosensitive drum 1, a compressing roller 6 which is separated from the intermediate transferring roller 5 and disposed and a photosensitive drum temperature sensor 7 which measures the surface temperature of the photosensitive drum 1. When the output value of photosensitive drum temperature sensor 7 is higher than the softening temperature of the toner particles, the liquid toner is cooled, the cooled liquid toner is supplied to the photosensitive drum 1 and the transfer efficiency is improved. |
