摘要： An image forming apparatus for collecting, through a developing device, and reusing remaining toner remained on a photosensitive drum, as an image carrier, for forming an electrostatic latent image, without being transferred to a transfer material, includes a toner uniforming member disposed between locations for a charging process and for an exposing process, for making the toner remained on the photosensitive drum during a transferring process adhere slightly and uniformly to the photosensitive drum. The toner uniforming member eliminates the remaining toner remained on the photosensitive drum temporarily, and is applied with a necessary voltage for making the remaining toner eliminated temporarily adhere to the surface of the photosensitive drum again.

摘要： In an electrophotographic printer, a power supply is connected to a transfer roller to which a current is supplied at a time that a print paper is inserted between a photosensitive drum 10 and the transfer roller. Since respective print papers have different resistances from one another, a voltage according to the kind of the print paper is generated at the transfer roller at a time that a preset current is supplied to the transfer roller, and is held. A sensor is arranged for detecting the width of the print paper, and detects the width of the print paper inserted between the photosensitive drum and the transfer roller. The value of the preset current supplied to the transfer roller 14 is changed so as to adapt to the width of the print paper.

摘要： An image-forming apparatus includes a toner-supplying roller and a developing roller assembled into a developing unit. The toner-supplying roller supplies toner to the developing roller. The developing roller applies the toner to an electrostatic latent image on a photoconductor to form a toner image. The toner image is transferred onto a print medium at a transfer unit, and finally fused into a permanent image at a fixing unit. The toner includes a wax that remains solid at room temperature and melts at a fixing temperature. At least one of the toner-supplying roller and the developing roller is a silicone roller on which oligomer in the form of siloxane is deposited. The silicone roller contains non-cured siloxane in the range of 10 to 8000 PPM.

摘要： A method of forming an electrostatic latent image includes printing operation and toner recovering operation. the printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

摘要： An image forming apparatus is capable of printing a position-coding pattern. A first print engine prints a position-coding pattern and holds a first developer material therein. A plurality of second print engines each print a corresponding image in accordance with print data, the image being different from the position-coding pattern, each of the second print engines holding a corresponding second developer material therein. The first developer material is charged to a first average amount of charge and has a first distribution of amount of charge. The second developer material is charged to a second average amount of charge and has a second distribution of amount of charge, such that the first average amount of charge is larger than the second average amount of charge, and that the first distribution of amount of charge has a smaller standard deviation than the second distribution of amount of charge.

摘要： In one embodiment, a method for reducing power consumption at a cache includes determining a nonuniform architecture for a cache providing an optimum number of cache ways for each cache set in the cache. The nonuniform architecture allows cache sets in the cache to have associativity values that differ from each other. The method also includes implementing the nonuniform architecture in the cache to reduce power consumption at the cache. In another embodiment, the method also includes determining a code placement according to which code is writeable to a memory separate from the cache. The code placement reduces occurrences of inter cache-line sequential flows when the code is loaded from the memory to the cache. The method also includes compiling the code according to the code placement and writing the code to the memory for subsequent loading from the memory to the cache according to the code placement to further reduce power consumption at the cache.
