An image forming apparatus includes an image forming portion for forming an image, an image reading portion for reading an image, displaceable with respect to the image forming portion, and an open/closable member that can be opened or closed with respect to a main body of the image forming portion and displaced toward the image reading portion, wherein the displacement of the open/closable member is effected in relation to the displacement of the image reading portion. In this manner the open/closable member can be opened or closed by a simple operation, without increasing the dimension of the image forming apparatus.
