    摘要： A transfer belt device having a roller unit. The roller unit includes a drive roller, a transfer roller, and a continuous transfer belt that is suspended around the roller unit. The drive roller rotates at a peripheral speed and drives the transfer belt such that a toner image may be transferred to it from an image carrier. The image carrier moves at a speed by means of the transfer roller. The drive roller is composed of a hard core roller that is coated with an outer layer of elastic rubber having a thickness t.ltoreq.1 mm, and is located downstream from the transfer roller in terms of the direction of movement of the transfer belt.

    摘要： An image forming apparatus includes a developing device that uses a developer carrier to advance to an image carrier a developer including a toner and a carrier and supplies the toner to the image carrier by applying a developing bias between the developer carrier and the image carrier. In the image forming apparatus, the following operation is performed before the developer in the developing device is taken out. The toner is supplied to the image carrier by applying the developing bias between the developer carrier and the image carrier, the developing bias increased in a direction to supply the toner to the image carrier. The toner supplied onto the image carrier is not transferred to a transfer receiving material but is advanced into a toner recovery device for recovery. The recovered toner is prevented from being returned to the developing device.

    摘要： A feeder has a longer side direction orthogonal to a conveyance direction of a recording medium, and is configured to feed a maximum size recording medium with a longer side first. An image forming unit has a maximum sheet feed width corresponding to a longer side length of the maximum size recording medium, and is configured to print a toner image corresponding to digital image data onto the recording medium. An electrical component unit is configured to control the feeder and the image forming unit. The image forming unit and the electrical component unit are respectively disposed on both sides of the feeder in a shorter side direction.

    摘要： An image forming apparatus includes a feeder having a longer side direction orthogonal to a conveyance direction of a recording medium, and feeds a maximum size recording medium with a longer side first, an image forming unit having a maximum sheet feed width corresponding to a longer side length of the maximum size recording medium, and prints a toner image onto the recording medium, and a sub feeder that can feed the maximum size recording medium to the image forming unit independently from the feeder. A post processing apparatus receives a printed recording medium and executes post processing on a side of the recording medium. A feeding source of the maximum size recording medium is selected from the feeder and the sub feeder for executing the post processing on the longer and shorter sides of the maximum size recording medium, respectively.

    摘要： A zoom lens system, for use in a copying apparatus, is provided with, from the object side, a first lens unit of a negative power including a negative lens element, a second lens unit of a positive power including a positive lens element and a negative meniscus lens element concave to the image side, an aperture stop, a third lens unit arranged symmetrically with the second lens unit with respect to the aperture stop, and a fourth lens unit arranged symmetrically with the first lens unit with respect to the aperture stop. The second lens unit and the fourth lens unit are moved in a same direction in association with each other so that the total length of the zoom lens system is minimum at unity magnification. The aperture stop moves so that the symmetry of the entire zoom lens system is maintained. An object-image distance is maintained constant by moving the entire zoom lens system.
