1. An image-forming apparatus comprising:

  • a plurality of image-holding members, each image-holding member holding an image and being rotatable around a rotation shaft;

    a frame member that at least partially defines a space for accommodating the plurality of image-holding members therein;

    a cover provided to the frame member to open and close the space with respect to an outside, an inner side of the cover being formed with rotation shaft insertion holes each for receiving an end portion of the rotation shaft of a corresponding one of the image-holding members accommodated in the space;

    a supporting shaft that supports the cover such that the cover is pivotable with respect to the frame member; and

    a positioning mechanism that positions the cover with respect to the frame member when the cover closes the space, the positioning mechanism including at least two projections that project from one of the frame member and the cover and that are spaced apart from each other in a direction of an axis of the supporting shaft such that lengths of perpendicular line segments from the at least two projections to the axis of the supporting shaft are different from each other, and projection insertion holes provided to the other one of the frame member and the cover to receive corresponding projections when the cover closes the space.
