FIXING DEVICE OF WET IMAGE FORMING DEVICE HAVING IMPROVED INITIAL IMAGE FIXING EFFICIENCY

摘要

PURPOSE: A fixing device of a wet image forming device having improved initial image fixing efficiency is provided to heat a heating roller and a fixing roller by separating the heating roller and the fixing roller at certain intervals, thereby uniformly heating surface temperature of the heating roller and the fixing roller in a ready mode and preventing deterioration of fixing performance. CONSTITUTION: A housing(20) has a paper entrance and a paper exit. A heating roller(10) is rotatively installed on a paper transfer path(33) of the housing(20), and builds the first heater(13) therein. The first temperature sensor(15) measures surface temperature of the heating roller(10). A pressure roller(12) is selectively adhered to the heating roller(10) within the housing(20). An interworking unit(24) enables the pressure roller(12) to interwork with an operation of a transfer roller(26) so that the pressure roller(12) is closely adhered to the heating roller(10). The pressure roller(12) comprises as follows. The second heater(14) is installed inside of the pressure roller(12). The second temperature sensor(16) is installed on one side of the housing(20) in order to measure surface temperature of the pressure roller(12).
