摘要： An image formation apparatus has a branching claw with a first guide surface along a side of a sheet to be fed into a reversing path and a second guide surface along a side of a sheet to be fed out of the reversing path. This branching claw is disposed so as to enable switching between a first switching position where the sheet is allowed to be fed into the reversing path through its conveyance along the first guide surface, and a second switching position where the sheet is allowed to be forwarded from the reversing path toward the downstream side of a sheet conveying path through its conveyance along the second guide surface.

摘要： An image forming apparatus, particularly a color image forming apparatus, of the present invention distinguishes a register mark and the background of a conveying member on the basis of the level of a signal representative of the background and the peak value or the bottom value of the signal. The apparatus can therefore accurately detect deviation between images of different colors and correct it.

摘要： A sheet feeder incorporated in an image forming apparatus and allowing the distance between the preceding sheet and the succeeding sheet to be reduced to a minimum necessary one. A pair of control rollers whose transport speed is controllable are located upstream of an image forming section with respect to an intended direction of sheet transport. An image transfer and paper separation unit is located at the image forming section. The transport speed of the control rollers is made higher than an image forming speed for any desired period of time after the leading edge of a sheet has been gripped by said control rollers and before the leading edge reaches the image forming section. As a result the distance between the preceding and succeeding sheets is reduced to increase the number of images which can be formed for a unit time without the transport speed at the image forming section being increased.

摘要： An image forming apparatus includes a deterioration determining device to determine a deterioration degree of a latent image bearer based on a potential detected by a surface potential detector. The deterioration determining device calculates a relative value indicating the deterioration degree based on the aggregated number of pixels and a time value for each of virtually divided regions. The deterioration determining device determines a deterioration degree of a detecting target region of the virtually divided region based on a potential detected by the surface potential detector. The deterioration determining device further determines deterioration degrees of non-detecting target respective regions of the virtually divided regions based on the relative values of the non-detecting target respective regions, the relative value of the detecting target region, and the deterioration degree of the detecting target region.
