PURPOSE: To provide a paper feeding device capable of surely preventing the generation of the skew and wrinkle of a paper sheet.

CONSTITUTION: The deflection quantity of a paper sheet 7 when the tip of the paper sheet 7 is made to abut on the nipping part of a registration roller 17 can be set according to the length of a carrying path to surely prevent the appearance of the skew and a wrinkle of the paper sheet 7 by providing plural paper feeding parts 3 different in the length of a paper feeding path to an image forming part 5 and setting a time, to stop a paper carrying body 15 from the point of time when the tip of the paper sheet 7 is detected by a resistration sensor 16, according to the length of the paper feeding path. The paper sheet 7 is bent by the further optimum condition to be butted to the registration roller 17 to more promote the generation preventive effect of the skew and wrinkle by correcting a time to stop the paper carrying body 15 from the point of time when the tip of the paper sheet 7 is detected by the registration sensor 16 while moreover considering the fluctuation, etc., in manufacturing an individual image forming device.
