    摘要： An image forming apparatus having a device for moving a charging roller towards and away from a photoreceptor and a cleaning member for the charging roller. The charging roller moving device moves the charging roller to positions including a first position where the charging roller is in contact with the photoreceptor and is separated from the cleaning member for a charging operation, a second position where the charging roller is in contact with the cleaning member for cleaning the surface of the charging roller and a third position where the charging roller is separated from the photoreceptor and the cleaning member. Even if the apparatus is left unoperated for a long time, the photoreceptor is prevented from being contaminated by the charging roller by placing the charging roller in the third position.

    摘要： In a developing device included in an electrophotographic image forming apparatus, a device for replenishing toner to the developing device has a toner container having a hollow cylindrical body. The body is formed with a toner outlet at the center of one end thereof. A holder arrangement holds the container such that the toner can be delivered to a toner inlet portion included in the developing device. A drive mechanism causes the container to rotate about its own axis. The holder arrangement is formed with an opening for feeding the toner flowing out via the toner outlet to the toner inlet portion. The opening is covered with an elastic member having a holed portion. The device is capable of replenishing a predetermined amount of toner to the developing device at all times.

    摘要： A transfer separator comprises a transfer belt or other transfer mechanism for carrying and conveying a sheet to apply a toner image from an image carrier onto the sheet and separating the sheet from the image carrier. A bias application electrode applies a transfer bias to the transfer belt, wherein a relation of Lp.gtoreq.aV, and a=1 mm/KV is established when the minimum distance between the image carrier and surface of the bias application electrode is set to Lp (mm) and the maximum voltage applied to the bias application electrode is set to V (KV) . Preferably, the bias application electrode has a coated layer, and the difference in thickness resistance between the coated layer and the transfer belt is within two orders of magnitude. The hardness of the coated layer is preferably equal to or greater than the hardness of the transfer belt.

    摘要： In an image transfer device for an image forming equipment, a bias for image transfer is applied from a power source to an endless transfer belt via a bias roller. A current from the Transfer belt is released to ground via a ground electrode. Transfer control means variably controls a current I.sub.1 output from the power source that the difference between the current I.sub.1 and a current I.sub.2 flowing from the power source to the ground via the transfer belt, i,e., I.sub.out =I.sub.1 -1.sub.2 remains at a preselected target current. Setting means sets the target current on the basis of a set condition or conditions.
