PURPOSE:To prevent the arrangement of respective parts of a paper feeding part from being restricted and any in the separating function from being generated, in an image forming device using a paper feeding roller formed into a fan shape in section. CONSTITUTION:The state where a partial dividing surface 2a of a paper feeding roller 2 is rolled and come in contact with a paper sheet so as to perform the paper feeding operation is detected by a pulse plate 5 and a photointerrupter 6, while the tip of the paper sheet is detected by a paper feed detecting switch 9. And the feed-out amount of the paper sheet is controlled on the basis of the output of the photointerrupter 6 from the time when the signal of the paper feed detecting switch 9 is input in a microcomputer 10, so that the paper feed- out operation of the paper feeding roller 2 is controlled on the basis of the result of the control. |
