摘要： A transfer apparatus for electrophotography is disclosed in which the resistance values of a transfer belt and the recording paper are measured, and the current value applied to a device for charging a member is set on the basis of the electrical resistance values. The charging device of the transfer belt is adapted to be taken up and reeled out and to circulate along a track. This configuration assures a stable transfer characteristic against the secular environmental variations of the component elements, lengthens the intervals of replacement of the charged member, and hence increases the mechanical life of the transfer apparatus and the electrophotographic apparatus using the same.

摘要： A multi-color image forming apparatus is capable of decreasing the amount of ozone generation which occurs during the formation of a multi-color image. For this purpose, a charged latent image having a tri-level electric potential is formed on a positive charging photoconductor by a charging means and an exposing means. A first color toner having one of a positive polarity and a negative polarity is caused to adhere onto one of the charged latent images having the highest electric potential level at a first developing unit of the apparatus, and a second color toner having the other polarity is caused to adhere onto the other of charged latent images having the lowest electric potential at a second developing unit of the apparatus. After that, the polarity of the toner having the negative polarity is reversed using a positive corona produced by a pre-transfer charging means to unify both polarities of the two color toners, and then both toners having the unified polarity are s transferred onto a sheet of paper.

摘要： An aerial recording sheet carrier is provided downstream of a fixing station. The aerial recording sheet carrier has one pair of pressure chambers with wall surfaces facing each other and in parallel. Air jets are arranged on opposite wall surfaces of the pressure chambers. A recording sheet and a toner image from the fixing station are carried by an air stream and cooled down. The toner image on the recording sheet, which is in fusion, is prevented from coming into contact with any parts, such as a recording sheet carrying passage. Thus a stain on parts due to contact with the toner image can be prevented.

摘要： A high-speed image forming method and apparatus is capable of directly controlling a toner by the force of an energy beam. Selected toner particles in a mass of toner adhering to the surface of a transparent drum are irradiated with a laser beam emitted by a laser disposed within the transparent drum and controlled for scanning according to image information. The laser beam separates the selected toner particles from the transparent drum by the force it produces on the particles, and then the separated toner particles are moved to a paper sheet by the force of an electric field produced by a developing electrode. Each toner particle need only be irradiated with the light for a comparatively short period of time, so that an image can be formed at high speed.

摘要： A dielectric belt 24 is retracted from a photoreceptor 2 before printing, and electrophotographic processes including a process of forming an electrostatic latent image, a developing process and a cleaning process except for a transferring process are repeated. During the repetition of the electrophotographic processes, a surface electric potential in the background of the photoreceptor 2 is measured by the electric potential sensor 10. Alternatively, a quantity of toner adhering to the background of the photoreceptor 2 is measured by the toner sensor 37 and the toner electric charge sensor 36. When the measured values are lower than the reference values, it is judged that no fringe image is generated in the recording condition, and the printing operation is carried out.

摘要： A toner of a first color incorporated into a development appartaus for second color is charged to a polarity opposite to a polarity of a charge of an electrostatic latent image for the second color by a frictional action with a toner in the development apparatus for the second color. The toner of the first color incorporated into the second development apparatus is caused to adhere to a charge-non-released region of a drum, whereby accumulation of the first toner in the second color development apparatus is prevented. The first and second toners are electrostatically transferred onto a paper by a bias electric field having a polarity opposite to that of the toner images, whereby at reversal development of the second color, the toner of the first color adhering to the charge-non-released region is prevented from being transferred onto the paper. Further, the toner of the first color, incorporated in the second development apparatus, changed reversly in its polarity, or reduced to about zero in the charge quantity can be removed by electrical and mechanical removal means provided in the second development apparatus.
