An image forming device includes a transportation path, a transportation
roller and a foreign particle collecting mechanism. The transportation
path extends approximately upward from a paper feed cassette which
sequentially feeds paper for printing an image. The transportation path
transports the paper from the paper feed cassette via an image forming
unit, which prints a desired image onto the paper, to a paper discharge
tray. The transportation roller is provided at the transportation path
upstream of the image forming unit. The foreign particle collecting
mechanism removes a foreign particle adhered to a roller surface of the
transportation roller. The paper feed cassette includes a container for
receiving a foreign particle dropped off from the foreign particle
collecting mechanism.
