摘要： 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.

摘要： An image forming apparatus includes a first image bearing member; a plurality of second image bearing members; an endless belt opposing the first and second image bearing members; a driving roller; a supporting roller; a first transfer member opposing the first image bearing member; a plurality of second transfer members provided opposing the second image bearing members; and a supporting member for supporting the second transfer members. The supporting member is movable between a first position as a contact position and a second position as a spaced position. When image formation is effected in a state in which the supporting member is positioned in the first position, a nip between the first image bearing member and the belt member is positioned to be spaced from a rectilinear line connecting contact positions of the belt member with the second image bearing members.

摘要： An image forming apparatus includes an image bearing member for bearing a toner image, a transfer member for transferring the toner image from the image bearing member onto a sheet in contact with the image bearing member, and an openable unit including an openable member and a rotational shaft. In addition, a lock member locks the openable unit in a closed state by movement of the openable member, and a cam member, provided in the main assembly, rotatably moves the transfer member toward and away from the image bearing member. A force receiving portion, provided on the openable unit, receives a reaction force in contact with the cam member. The openable member includes the transfer member, and the cam member urges the force receiving portion when rotated to impart a force, for attracting the openable unit toward a locking direction by the lock member, to the openable member.
