A photoreceptor web for an image forming apparatus includes a base layer, a conductive ground layer formed on the base layer, and a photosensitive layer formed on the ground layer, where an electrostatic latent image is formed by scanned light. A first protective layer is formed on the photosensitive layer for protecting the photosensitive layer, and a heating layer is formed on a rear surface of the base layer in a predetermined pattern for receiving electric power and generating resistance heat. The photoreceptor web is maintained at a constant temperature by the resistance heat generated by the heating layer.

An apparatus and a method of removing a photoreceptor belt from an electrophotographic printer are provided. The apparatus includes at least one pair of rollers for pressing and transferring the photoreceptor belt circulating in a predetermined traveling track, a cutting blade capable of cutting the photoreceptor belt while moving across the photoreceptor belt, a cylindrical member rotatably installed in a filter housing disposed near the photoreceptor belt, the filter housing having a filter cartridge for filtering foreign material of the inner air of the printer, and a driver for rotating the cylindrical member such that the photoreceptor belt is wound around the cylindrical member. The photoreceptor belt is cut and automatically drawn from the traveling track into the filter housing. The cut photoreceptor belt is removed together with the filter cartridge installed in the filter housing. The photoreceptor belt removing process can be easily and quickly performed, and it is also convenient to manage a replacement cycle of supplies for a printer.

The present invention relates to a method for forming silicon oxide films on substrates using an atomic layer deposition process. Specifically, the silicon oxide films are formed at low temperature and high deposition rate via the atomic layer deposition process using a Si2Cl6 source unlike a conventional atomic layer deposition process using a SiCl4 source. The atomic layer deposition apparatus used in the above process can be in-situ cleaned effectively at low temperature using a HF gas or a mixture gas of HF gas and gas containing —OH group.
