摘要： The object of the invention is to provide a transfer apparatus including a transfer drum which carries a transfer material by electrostatic attraction with reliability, and can prevent the transfer nonuniformity of the image. The transfer drum is so formed that on the surface of a dielectric layer made of cylinder-shaped aluminium, are formed side by side two semiconductor layers each formed by a foamed elastic member, and on the surface of the semiconductor layers are stacked a conductive layer formed by PVDF. The first semiconductor layer is formed under the transfer region within the surface of the transfer drum, and the diameter of cell is set to be in a range of over 0 .mu.m to 50 .mu.m. Also, the second semiconductor layer is formed under the non-transfer region within the surface of the transfer drum, and the diameter of cell is set to a size of 500 .mu.m or more.

摘要： Deteriorating developer including toner and carrier in a developer container is replaced by supplying carrier developer including carrier from a developer supply unit and discharging an amount of the deteriorated developer corresponding to the amount of the supplied carrier developer through a discharge opening formed in the developer container by opening a cover. The cover is driven by a solenoid for discharging. With this structure, even when the amount of developer in the developer container is changed and the surface level of the developer is changed, a predetermined amount of deteriorated developer is accurately discharged according to the driving of the cover. It is thus possible to control in a desired manner the replacement ratio of deteriorated developer in the developer container to new developer to be supplied. With this configuration, it is possible to maintain the charge of developer substantially uniform and good image quality of copies.

摘要： In a new printer, a toner cartridge is mounted in the state where there is no toner in a reserve tank, and toner of the amount of filling toner D therein is supplied with the amount of full accommodation toner E for filling up the reserve tank by a toner supply mechanism. The toner of the amount of remaining surplus toner F remains in the toner cartridge. The amount of toner consumption G is measured by a dot counter during a printing execution. In the case where a toner density sensor detects a toner decreasing, the toner is supplied to a developing unit from the reserve tank. When it becomes G>F, it display-informs a user of “toner cartridge exchange is allowed”. Hereby, it enables to exchange the toner cartridge without stopping operation of the main body of the image forming apparatus using a two-component developer.

摘要： An intermediate transfer belt is built in an electro-photographic image forming apparatus. A toner image formed on a photosensitive element is primary transferred on the intermediate transfer belt. The intermediate transfer belt secondary transfers the primary transferred toner image on a recording medium being conveyed at a secondary transfer unit. The intermediate transfer belt has streaks formed by surface roughening on the surface thereof and directed so as to have an angle relative to the driving direction of the intermediate transfer belt within a range from 40 to 140 degree. This angle setting enables stable transfer of an image without causing any character missing.

摘要： An idle roller on which a dielectric belt is wound is made up of a metal such as aluminum etc., and is used as a charging device. A voltage is applied to this idle roller from a d.c. power source.

摘要： When a grounded conductive roller touches a transfer drum through a transfer material while a voltage is applied to a conductor layer, charges having a polarity opposite to the polarity of the voltage applied to the conductor layer are generated over the transfer material, thereby making it possible to attract the transfer material to the dielectric layer. Since the voltage is applied to the conductor layer, the electrostatic attraction of the transfer material and the toner transfer can be carried out using a single power source. Moreover, since the attraction of the transfer material and the toner transfer are carried out by the charge injection, a lower voltage can be used. Thus, the voltage can be readily controlled while reducing the ozone emission to a relatively low level. Furthermore, since the toner transfer and electrostatic attraction of the transfer material can be carried out using a single power source, the apparatus can be downsized and less expensive. In addition, when a semiconductor layer is made of a solid elastic body, a high-quality transferred toner image can be obtained without image quality deterioration.

摘要： An image forming apparatus is provided with a photosensitive drum on whose surface a toner image is formed, and image formation is carried out by transferring the toner image onto a transfer material such as paper or OHP sheet which is caused to electrostatically adhere to a surface of a transfer drum while being guided to the photosensitive drum. Alternatively, the toner image formed on the photosensitive drum may be once transferred onto an intermediate transfer drum, then transferred from the intermediate transfer drum onto the transfer material. In the image forming apparatus, a light projecting device for projecting light onto the photosensitive drum is provided on an upstream side to a toner image transfer position and on a downstream side to a development position on the photosensitive drum. Execution and suspension of the light projecting operation of the light projecting device is controlled depending on a toner type.
