摘要： A method of manufacturing a charge roller utilizes a foam rubber substance where epichlorohydrin oxide rubber and an acrylonitrile butadiene rubber are mixed at a ratio of 5:95, or utilizing a crosslinking rubber substance consisting of epichlorohydrin oxide rubber and acrylonitrile butadiene rubber having a polar low molecular polymeric characteristic, thus allowing the charge roller to maintain a low volume resistivity of 107 &OHgr; cm to 108 &OHgr; cm. As a result, the surface of a photosensitive drum can be charged by a minimum charging voltage, to thereby significantly reduce an amount of ozone. A method of manufacturing a charge roller employs peroxide as a cross linking agent for rapidly cross-linking molecular chains between an epichlorohydrin oxide rubber and acrylonitrile butadiene rubber forming a main composition of a foam rubber substance. Since a non-crosslinked low molecular polymeric substance existing at a resilient rubber is significantly reduced, the low molecular polymeric substance of the charge roller may not be migrated onto a surface of the photosensitive drum even if the charge roller is in contact with a photosensitive drum for a long time period during a stoppage of operation of an image forming apparatus, As a result, the charge roller may not cause an abnormal phenomenon on the surface of the photosensitive drum.

摘要： The present invention provides a developing device of an electrophotographic recording system for developing an electrostatic latent image formed on a photosensitive drum. The developing device includes a hopper which stores toner and a developing roller which develops the electrostatic latent image formed on the photosensitive drum using the toner stored in the hopper. On one side of the hopper at a predetermined height from its bottom, a light-emitting element for emitting light is positioned. A toner detecting device detects the existence or non-existence of toner by using a light-receiving element positioned on the interior of the hopper which outputs signals corresponding to the existence or non-existence of toner in the hopper in response to the amount of the light received from the light-emitting element. An agitator conveys the toner to the developing roller and simultaneously cleans a light-emitting side of the light-emitting element and a light-receiving side of the light-receiving element in synchronism with a conveyance period of the toner. A signal transmitting device transmits signals from the light-receiving element to a CPU which compares the number of signals with a predetermined value, thereby determining a level of the toner.
