The object of the present invention is to provide a paper feeding device of frictionally separating roller mechanism, which assuredly handle and separate sheets without using a torque limiter even if environmental factors such as temperature, humidity and etc. are changed. In order to achieve the object, the paper feeding device of the present invention comprises a paper feed roller 3 and reverse roller 6, both of which are made with polynorbornene rubber, and the rubber of the paper feed roller 3 is thicker by 0.5 mm than that of the reverse roller 6.
