    摘要： An application device includes a conveyer to convey a recording medium, an application roller to apply a treatment liquid to the recording medium, a pressure roller to sandwich the recording medium with the application roller to press the recording medium against the application roller, and a winding member to form a curved conveying path to have the recording medium curved along a conveying direction to wind the recording medium around the pressure roller. The pressure roller comes in contact with the application roller when applying the treatment liquid and separates from the application roller when not applying the treatment liquid. A predetermined positional relationship is maintained between the pressure roller and the winding member while the pressure roller moves close to the application roller to be in contact with the application roller, or the pressure roller moves away from the application roller to be separated from the application roller.

    摘要： Apparatus that forms an image according to image information includes density sensors that detect image density variations in main and sub-scanning directions. A processing device generates correction data for correcting a light source output to suppress the density variations based on detection results. The processing device modifies the correction data such that the light source output after the correction is at least a minimum rated output at a position at which the output after the correction is lower than the minimum rated output, in the relation between a position on the surface of the photosensitive element in the main-scanning direction and the output after the correction, and modifies the correction data such that the light source output after the correction is at most a maximum rated output at a position at which the output after the correction is higher than the maximum rated output.

    摘要： A disclosed light source apparatus includes a light source including multiple light emitting devices; an optical element configured to transmit light emitted from the light source; a tube configured to hold the optical element; and a tube holder configured to fix the tube by holding an end of the tube close to the light source or by holding the end of the tube on the light emission side away from the light source. A positional displacement preventing member is provided at the other end of the tube on a light emission side away from the light source in such a manner as to be slidable on the tube in the direction of an optical axis and prevent positional displacement of the tube in all directions perpendicular to the optical axis.
