    • PROBLEM TO BE SOLVED: To provide an image forming device and a paper feeder capable of smoothly conveying paper by carrying out paper powder removal processing by a paper powder suction roller and a paper powder removing member in a small installation space.
      SOLUTION: A laser printer 1 has a paper powder removing unit 70 including the paper powder suction roller 71, the paper powder removing member 73, and a support frame 75. In image formation, paper 5 is conveyed to the paper powder removing unit 70 via either one of a first conveying passage R or a second conveying passage M. In the paper powder removing unit 70, the paper 5 is contacted to a guide part 76, and it rocks the support frame 75. At this time, the guide part 76 smoothly guides the paper 5 along the conveying passage. The paper powder suction roller 71 is contacted to the paper 5 guided by the guide part 76, and paper powder P is removed. The paper powder P adhered to the paper powder suction roller 71 is removed from the paper powder suction roller 71 by contact with the paper powder removing member 73, and it is dropped to a paper powder receiving part 78 by rocking of the support frame 75 following contact with the paper 5.
