A through anchor in which residual stress caused by thermal contraction is dispersed so as to reduce risk of crack formation in a resin molding portion. The through anchor includes a metal plate and a resin molding portion covering a portion of the metal plate. Usually, residual stress due to thermal contraction (shrinkage) differences between the resin molding portion and the metal plate is high in regions near both ends of the boundary between the resin molding portion and the metal plate. A notch portion is formed in each of the regions so as to expose a portion of the outer peripheral portion of the metal plate covered by the resin molding portion to the outside environment. Accordingly, although the resin molding portion thermally contracts after insert molding, the contraction of the resin molding portion is not retarded as much by the outer peripheral portion of the metal plate due to the outer peripheral portion of the metal plate being exposed. As a result, the risk of crack formation in the resin molding portion is reduced in this region.

An image forming apparatus includes a communications line for connecting the image forming apparatus to other image forming apparatuses to create a system of a plurality of image forming apparatuses; a device for setting a connected printing mode to allocate and print jobs to be printed by the plurality of image forming apparatuses; a device for executing printing in the connected printing mode by the plurality of image forming apparatuses; and a device for releasing the use of the image forming apparatus under the connected printing mode when the image forming apparatus receives a print command while a printing operation is being executed by the plurality of image forming apparatuses under the connected printing mode.
