Slide rail, paper feeder, and image forming apparatus

A paper feeder comprising:

• a pull-out paper feeding tray configured to accommodate paper sheets to be fed;
• and
• a pair of the slide rails configured to be attached to left and right sides of the paper feeding tray in order to guide the paper feeding tray in a pulling direction, wherein,
• each of the pair of the slide rails comprises;
• a fixed rail,
• a movable rail configured to be slidably attached to the fixed rail, and
• a roller configured to be attached to at least one of the fixed rail and the movable rail and runs on the other one of the fixed rail and the movable rail as the movable rail slides,
• the other one of the fixed rail and the movable rail including a running wall on which the roller runs and sliding contact walls that come into sliding contact with opposite side surfaces, in a direction of a rotation axis of the roller, of the roller, wherein
• the roller includes a metal-made roller main body and a pair of resin-made sliding plates that sandwich the roller main body from opposite sides thereof in the direction of the rotation axis of the roller, and
• the pair of sliding plates are in sliding contact with the sliding contact walls.
