The developing device produces a developed image desirable in quality and free from background fogging when the magnitude of a developing electric current, I (A), is adjusted so as to satisfy the formula, R.ltoreq.200/I. Further, when a charging device, an electrostatic latent image forming device, a transfer device, a cleaning device, a discharge device, a charging and cleaning device, an electrostatic latent image forming and cleaning device, a developing and cleaning device, or a discharging and cleaning device is provided with an elastic electroconductive roller composed of an elastic roller base and a flexible conductor layer, the device is allowed to decrease size and lower price, curb the decline of capacity due to protracted use, and preclude the occurrence of dispersion of characteristic, efficiency, or performance.

摘要： A transfer device for transferring a toner image on an image carrier onto a transfer material, including a transfer drum, a supporting device for the transfer material in place on the surface of the transfer drum and an electrode for applying a bias voltage to an electroconductive layer of the transfer drum. The transfer drum includes a rotatably supported drum member, a flexible elastomer layer on the peripheral surface of the drum member, and an electroconductive layer on the elastomer layer. The elastomer layer of the transfer drum is made of a foaming elastomer such as a polyurethane foam so that the transfer material is in contact with the toner image on the image carrier under a small amount of pressure and with an ample contact width.
