Image forming apparatus that prevents damage of multi-tray cover and relay device cover

An image forming apparatus, comprising:

• an image forming apparatus body;
• a multi-tray device including a plurality of sheet discharge trays located in a vertical direction, the multi-tray device being mounted on a side surface of the image forming apparatus body;
• and
• a relay device disposed over the image forming apparatus body, the relay device conveying a paper sheet discharged from the image forming apparatus body to the multi-tray device,
• wherein the multi-tray device includes a multi-tray cover that turns around an axis extending in the vertical direction as a pivot to openably and closably cover a side of the relay device of the multi-tray device,
• the relay device includes a relay device cover that turns around an axis extending in a horizontal direction as the pivot to openably and closably cover a top side of the relay device,
• one of an edge portion at a side of the relay device in a lower end portion of the multi-tray cover and an edge portion at a side of the multi-tray device in a top surface portion of the relay device cover includes an inclined surface portion forming a shape by chamfering the edge portion, and
• the inclined surface portion is formed so as to produce a component force in a direction to close the multi-tray cover when the top surface portion of the relay device cover bumps against the lower end portion of the multi-tray cover, while the relay device cover opens in a state where the multi-tray cover is opened.
