摘要:
A paper feed roller-producing method is to be provided, which enables more inexpensive mass produce of a high precision paper feed roller, with a high precision, having no connecting portion in a roller portion, by using a hydraulic composition. The method for producing a paper feed roller includes a rotary shaft and a cylindrical roller portion integrated around an outer periphery of the rotary shaft, characterized in that the roller portion is formed by extruding a hydraulic composition and curing and hardening the extrudate.
