摘要： A magnetic roller comprising a diamagnetic cylinder rotatable about magnetic poles which extend axially inside the cylinder and are each formed by similar poles of magnets lying axially beside each other is made to generate a substantially homogeneous magnetic field over its full working width, thus enabling the magnets to be made of strongly ferromagnetic, anisotropic material, by the provision, over and along one or more of the magnetic poles between the magnetic pole and the diamagnetic cylinder, of a material having high magnetic permeability, such as a strip of soft iron of between 0.1 and 1 mm. in thickness fixed to and not wider than the surface of the magnetic pole. The magnetic roller is especially useful in electrophotographic developing apparatus for transporting magnetically attractable developing powder between a powder reservoir and a developing zone in which powder from a magnetic brush formed on the cylinder is applied to electrostatic images on imagewise exposed photoconductive sheet material.

摘要： A stable panchromatically sensitized zinc oxide having a low moisture sensitivity with dark discharge properties rendering it suitable as the photoconductive material of elements for indirect as well as direct electrophotography is produced by reacting finely divided zinc oxide with gaseous ammonia and carbon dioxide, while keeping the zinc oxide particles in motion, until a critical stage is reached corresponding usually to a weight increase of 4 to 7.5%, at which point the reacting is terminated and the product is heated to constant weight at a temperature between 190.degree. and 350.degree. C. Photoconductive elements made with the panchromatically sensitive zinc oxide not only are reusable indefinitely under varying atmospheric humidity conditions without loss of their sensitivity, but also exhibit a memory effect much lower than that of known photoconductive zinc oxides.

摘要： Vinylpyrene (substituted or not) is prepared in a single reaction stage by reacting the corresponding acetylpyrene with a metal alkoxide, e.g. aluminum isopropoxide, in an inert organic solvent, e.g. a xylene, at a temperature above 110.degree. C. which, for some reaction conditions, optimally is between 130.degree. and 150.degree. C. The presence of hydroquinone in the mixture reduces the time and increases the yield of the reaction.

摘要： Images of fusible toner particles on flexible sheet material, such as applied to paper sheets in electrostatic photocopying machines, are fixed to the material by feeding it through a heating zone in which the particles are softened without fusing them and then passing the material through the nip between smooth rigid pressure roller surfaces which are constantly pressed together under a force sufficiently great to join the heated toner particles superficially one to another and to the sheet structure without forming them into brittle resinous films. An apparatus for carrying out the fixing comprises a set of smooth rigid feed rollers constantly pressed together, preferably by structures like those used for the pressure rollers, under a selected pressure suited for advancing the material into and through a radiant heating zone at a constant speed and thence into the nip of the pressure rollers which are driven at the same peripheral speed.

摘要： For fixing electrostatically formed images of thermoplastic powder on copy sheets, an elastic roller and a heated rigid roller form a nip through which each sheet is passed with its image side engaged by the elastic roller, and the elastic roller has a pliable annular body formed with circumferential surface grooves or ribs which cooperate with organs of complementary form for separating each sheet from the roller surface behind the nip, yet which provide an even roller surface in the nip by being elastically deformed therein. The rigid roller is formed with circumferential surface grooves which also cooperate with complementary sheet separating organs. The separating organs cooperating with grooves may be blades extending into them behind the nip, or wires extending in them through the nip; those cooperating with ribs may be blades having profiled edges held almost in contact with ribbed regions of the elastic roller surface.

摘要： Reproduction elements coated with organic photoconductors are made with improved and/or more widely selectable electrophotographic properties by employing in the photoconductive coating a donor-acceptor complex composed of a known organic electron donor having photo- or semiconductor properties, e.g. a poly-N-vinylcarbazole or polyvinylpyrene, and a N-(fluoren-9-ylidene)-aniline compound as an activating electron acceptor. Especially effective as the electron acceptor are certain new compounds, namely, p- and m-nitro-N-(2,4,7-trinitrofluoren-9-ylidene)-aniline and p-methylsulfonyl-N-(2,4,7-trinitrofluoren-9-ylidene)-aniline.

摘要： For control of an indirect electrophotographic copier employing an endless photoconductive belt having thereon at least one marking which excites a sensor each time the marking passes a fixed point in the belt path, the movement of the belt is measured electronically by a pulse generator coupled to a belt transport roller and a counter. Any difference between an electronically registered length of the belt and its actual length at a moment of sensor excitation is registered in a memory. At the end of a copying run pulses from the generator are diverted to the memory which then causes the difference to be corrected by discontinuation of the driving of the belt at an earlier or later moment.
