摘要： An image forming apparatus having a unit for charging the surface of an image carrier uniformly with electricity, a unit for forming an electrostatic latent image on the surface of the image carrier charged electrically, a unit for developing the electrostatic latent image formed on the surface of the image carrier to thereby form a toner image and a means for transferring and fixing the toner image to a transfer member. The developing unit includes a developing roller which is disposed so as to contact the image carrier. The developing roller is connected to a power source for charging the toner particles on the developing roller with electricity with the same polarity as the charging polarity of the the image carrier, and for applying an electric potential to the developing roller so that the toner particles remaining on the developing roller are stuck to an image portion of the image carrier and the toner particles remaining on a non-image portion of the image carrier are attracted by the developing roller. The developing roller rotates in the direction opposite to that of the image carrier and a peripheral velocity of the developing roller exceeds 1.2 times that of the image carrier. Since the collected toner particles are not necessary to be disposed of, the environment is not polluted and the efficiency of using the toner is improved.

摘要： In an electrophotographic recording device which includes a number of consumable parts, there is provided a first memory for storing a currently integrated total number of prints, and a number of prints at replacement of each consumable part. A second memory stores a number of lifetime prints, which is a conversion of the life of each part into a number of prints. A processor performs a first calculation to calculate a number of prints for replaced consumable parts after such replacement and a second calculation to calculate a wear rate of the replaced consumable parts from the number of lifetime prints read out from the second memory, and from the number of prints calculated by the first calculation. An indication section indicates the wear rate obtained from the second calculation. The number of prints stored in the first memory for the consumable parts at replacement is written into the current total number of prints.

摘要： A developing apparatus includes a developing roller, a first shaft, a second shaft, a belt, and a power supply. The developing roller is in contact with an image forming body. The first shaft is driven in rotation by an external drive source. The belt is entrained about the first and second shafts, and is partially at first and second portions in a wrapping contact with the developing roller. The power supply applies voltages to the first and second shafts such that a voltage drop appears in the belt in a direction of travel of the belt. The power supply applies a voltage to the developing roller such that a first electric field is developed across the developing roller and the first portion, and such that a second electric field in the opposite direction to the first electric field is developed across the developing roller and the second portion.
