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 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.
摘要翻译：图像形成装置包括用于承载调色剂图像的图像承载部件，用于将调色剂图像从图像承载部件转印到与图像承载部件接触的片材上的转印部件，以及包括可打开部件和旋转部件的可打开单元轴。此外，锁定构件通过可打开构件的移动将打开单元锁定在关闭状态，并且设置在主组件中的凸轮构件可转动地将转印构件朝图像承载构件移动并远离图像承载构件。设置在可打开单元上的力接收部分接收与凸轮构件接触的反作用力。可打开构件包括转印构件，并且当旋转时凸轮构件推动力接收部分，以赋予可打开单元以将锁定构件朝向锁定方向吸引到可打开构件的力。
