    Abstract: In an image forming apparatus, the number of components and a size of the apparatus is reduced by realizing both functions for detecting a toner patch image to perform image quality adjustment and for performing precise color adjustment depending on a sheet color with one color sensor. The color sensor is disposed in a vicinity of a transport belt, a reference toner image is formed on the transport belt at a predetermined timing. A color of the reference toner image formed on the belt is detected by the color sensor to adjust development conditions. Further, the sheet is transported in a state where the transport belt is separated from a photoreceptor drum, and the sheet color is detected by the color sensor, and thereafter the transport belt touches the photoreceptor drum to transport the sheet to a transfer portion.

    Abstract: An image forming apparatus, which realizes a buffering function which enables post-processing without decreasing the productivity and increasing the size. At least one image is formed on a sheet. A double-sided sheet conveying path is provided, which the sheet passes when being conveyed back to the image forming unit again to form an image on an opposite side surface of the sheet after an image is formed on one side surface of the sheet. A retaining member is provided on the double-sided sheet conveying path to retain the sheet on the double-sided sheet conveying path. A post-processing device carries out post-processing on sheets on which images have been formed by the image forming unit. A CPU circuit section, which controls conveyance of the sheet, provides control to convey the sheet on which the at least one image has been formed by the image forming unit to the double-sided sheet conveying path, cause the retaining member to temporarily retain the sheet on the double-sided sheet conveying path, and then convey the sheet to the post-processing device.

    Abstract: Image forming apparatus including a paper return device for feeding a sheet of paper ejected from a paper output port opening in a main body of the apparatus to its outside back to a paper feeding port also opening in the main body to its outside. For double-sided copying operation, the sheet of paper ejected from the paper output port carrying an image on one side only is returned to the paper feeding port and fed again to an image former from the paper feeding port so that it is not necessary to provide a dedicated paper path for re-feeding the paper. The apparatus includes a paper sensor which senses the paper inserted into the paper feeding port and outputs a paper sensing signal, a discriminator for judging whether the paper return device is in an operating condition, and a paper feed controller which controls a driver for driving a paper feeder such that the paper feeder initiates a paper feed operation when the paper sensing signal is output while the paper return device is in its operating condition.
