A support stand includes: scanner attachment portions to which one end portion and the other end portion of a scanner along a scanning direction are attached; a scanner fixing structure that fixes the one end portion of the scanner to the scanner attachment portions; and a scanner attachment structure that attaches the other end portion of the scanner to the scanner attachment portions such that the other end portion of the scanner is movable along the scanning direction.

Support stand, scanner device, and image recording apparatus

An image forming apparatus includes an image carrier which has a predetermined center of rotation and on which a toner image is formed, a developing device which has a developing roll that rotates while carrying a toner on the surface thereof and that conveys the toner to a developing position, an intermediate transfer member which is disposed in an approximately flat shape and circulatingly moves, and a fixing unit which fixes the toner image on the transfer material thereon at a predetermined fixing position. In the image forming apparatus arranged as described above, both the image carrier and the developing roll are disposed in a triangle region formed by the approximately flat-shaped intermediate transfer member, a vertical line in contact with the intermediate transfer member, and a horizontal line in contact with the intermediate transfer member, thereby the size of the image forming apparatus can be more reduced.

Image forming apparatus

An image forming apparatus includes an intermediate transfer member having at least one short surface and two elongated surfaces and held so as to be substantially a flat shape, and an intermediate transfer member cleaner provided on the short surface of the intermediate transfer member for removing toner attached to the surface of the intermediate transfer member. The intermedaite transfer member cleaner includes a scraper provided on the upstream side of the intermediate transfer member in the direction of rotation and a brash rollerprovided on the downstream side in the direction of rotation.

Image forming apparatus, replacement unit and cleaner

An image forming apparatus is provided with a photosensitive drum in which a toner image is formed on surface thereof; an intermediate transfer belt to which the toner image of the photosensitive drum is transferred via a primary transfer portion and the transferred toner image is transferred via a secondary transfer portion to a paper; and a wrap-out roller which abuts against a rear surface of this intermediate transfer belt so as to apply tension to the intermediate transfer belt. This wrap-out roller forms the primary transfer portion which causes the intermediate transfer belt to abut against the photosensitive drum in a wrap shape, and forms a flat plane portion toward the secondary transfer portion. This wrap-out roller is arranged within a projection area which is directed from a secondary transfer roller toward the photosensitive drum.

A sheet size detection device for detecting a size of sheets which are held in a cassette body comprises a first guide member for defining the position of the sheets which are held in the body of the cassette, in a first direction of the sheets, the first guide member being movable in accordance with the size of sheets, a second guide member for defining the position of the sheets, in a second direction of the sheets, the second direction being orthogonal to the first direction, the second guide member being movable in accordance with the size of sheets, a first arm having a first resistor and movable with the first guide member, a second arm having a second resistor and movable with the second guide member, the first and second resistors constituting a variable resistor, and a size detector for detecting the size of the sheets on the basis of the resistance value of the variable resistor.
