    Abstract: An apparatus for topping off a fuel tank which is necessary for full tank delivery after false fuel level detection caused by fuel bubbles or splashes. This is made possible by making a spring biased valve sent for a main valve longitudinally movable and providing control means and a mechanism so that despite a trigger being in the actuated position the valve is opened when bubbles or splashes disappear.

    Abstract: A transfer device according to the present invention have a current detector for detecting a value of an upstream current flowing from an intermediate transfer belt into a tension roller, a transfer bias power source for performing control in such a manner as to prevent any further increase in output voltage value even if an output current value becomes lower than a value which should be subjected to a constant-current control in the case where an output signal from the current detector is a signal indicating 3.2 &mgr;A. Consequently, it is possible to suppress the unclearness of the edge of a transfer image caused by the upstream current flowing in a visible image carrying belt upstream of a transfer position such as a nip.

    Abstract: In an electrostatic image forming apparatus, including a corona discharger located so as to face an image carrier on which a toner image is to be formed. When a paper or similar recording medium is brought between the image carrier and the discharger, the discharger effects corona discharge at the rear of the recording medium so as to charge the medium to a polarity opposite to the polarity of the toner image. The toner image is transferred from the image carrier to the recording medium. A polarity switcher allows a voltage of substantially the same polarity as the toner to be applied to a discharge wire included in the discharger. The apparatus is free from defective discharge and defective image transfer ascribable to the deposition of free or isolated toner on the discharger.

    Abstract: An image forming apparatus of the present invention includes an intermediate transfer belt to which a toner image is transferred from an image carrier. A transfer roller contacts the intermediate transfer belt, forming a nip for image transfer. The transfer roller causes the toner image to be transferred from the intermediate transfer belt to a recording medium at the nip. A first and a second guide member cooperate to guide the recording medium to the nip. The end of the second guide member is positioned at the intermediate transfer belt side with respect to a line connecting a restriction point included in the first guide member and the inlet of the nip. This configuration causes a portion of the recording medium rearward of a portion entered the nip to bend in a convex configuration. The recording medium therefore surely remains in close contact with the intermediate transfer belt in a region where pretransfer is apt to occur.

    Abstract: An image forming apparatus which utilizes an intermediate transfer member. Plural toner images, for example of different colors, can be superimposed on the intermediate transfer member, and then can be transferred to a paper sheet. A discharging device is provided for discharging a charge applied to the intermediate transfer member. Further, a value of a voltage provided by this discharging device and/or a voltage provided for a transfer bias is proportional to an actual surface potential on the intermediate transfer member, which is proportional to the number of times toner images have been formed on the intermediate transfer member prior to transfer to the paper sheet. For example, if a full color toner image is formed on the intermediate transfer member, which may result from four operations of transferring individual toner images onto the intermediate transfer member, a voltage provided by the discharger and/or by a transfer bias device will be higher than that if only a monocolor image has been formed on the intermediate transfer member. Further, the image forming apparatus can be operable to form images on thicker paper, and in this instance a drive speed of devices in the image forming apparatus can be reduced, and a voltage applied to a pre-charger can also accordingly be reduced. The image forming apparatus can also include a cleaning device from the intermediate transfer belt, and the functions of both the intermediate transfer member discharging device and a cleaning device can be combined in one brush roller.
