An image forming apparatus includes an openable cover, including a rotational shaft, capable of opening and closing an opening by being rotated about the rotational shaft relative to a main assembly of the image forming apparatus; an image forming portion for forming a toner image on a sheet; an opposing member, provided in the image forming portion, opposing the openable cover when the openable cover closes the opening; a contact member, provided on the openable cover, contactable to the opposing member; an urging member, provided on the openable cover, for urging the contact member toward the opposing member; and a locking member for locking the openable cover in a closed state relative to the main assembly. The image forming apparatus comprising a cam member, provided in the image forming portion, for moving the contact member toward and away from the opposing member by rotation of the cam member. The cam member has a shape such that when the contact member is contacted to the opposing member in a state in which the openable cover is not locked by the locking member, the cam member applies a force to the openable cover in a direction, in which the opening is open, by rotation thereof and then applies a force to the openable cover in a direction, in which the opening is closed, by rotation thereof.
