    摘要： An image reading apparatus for reading a document image includes: a document feeding tray for placing the document thereon; a first document reading position for reading the first face of the document ejected and conveyed each from the document feeding tray; a document reverse tray for storing the document so that the document having passed through the first document reading position is reversed and conveyed; a stationary document reading position wherein the document having passed through the document reverse tray and having been reversed and conveyed is conveyed to a platen and the stationary document is read; and an image reading unit for reading the document image. The image reading unit stops at the first document reading position to read the first face of the document, and performs scanning movement at the stationary document reading position to read the second face of the document.

    摘要： An image forming apparatus includes a photoreceptor member; a LED head that includes a plurality of light emitting diodes arrayed in a line along a rotating axial direction of said photoreceptor member and that is modulated in response to image signals, so as to expose said photoreceptor member while said photoreceptor member is rotating; a deviation detecting sensor to detect deviations on a circumferential surface of said photoreceptor member; a filter to extract low frequency components including a rotational frequency component of said photoreceptor member from deviation signals detected by said deviation detecting sensor, so as to acquire deviation information with respect to said circumferential surface of said photoreceptor member; a driving section to move said LED head back and forth against said circumferential surface of said photoreceptor member; and a position controlling section to control said driving section, based on said deviation information acquired by said filter, so as to keep a distance between said LED head and said circumferential surface of said photoreceptor member constant.
