Paper feed tray and image forming apparatus

A paper feed tray comprising:

• a cassette in which a sheet of paper is placed;
• a regulation plate which is slidably attached to the cassette and regulates a position of the sheet of paper;
• a cover provided to the regulation plate;
• a locking portion which is covered with the cover and engages with the cassette to fix a position of the regulation plate;
• and
• a lever including a coupling portion covered with the cover and coupled with the locking portion, a depression portion configured to be depressed toward one side in a direction of sliding of the regulation plate, and an intermediate portion provided between the coupling portion and the depression portion, the lever operating the locking portion to be disengaged from the cassette upon the depression portion being depressed toward the one side, wherein
• the cover includes an extension provided opposite to the one side with the lever therebetween and extending while facing the intermediate portion, and
• a space is provided between the extension and the intermediate portion, the space being open at a tip to which the extension extends,
• wherein the cover further includes a protrusion projecting from the extension toward the intermediate portion.
