Abstract: PURPOSE:To prevent a recording head from being abraded ad to stably for a high-resolution recorded image by juxtaposing plural recording electrodes in a direction perpendicular to a developer carrying direction and forming the surface of a part which extends to the recording part of the recording electrode of a magnetic material. CONSTITUTION:The plural recording electrodes 15b are juxtaposed and installed with a very small gap between a cylindrical electrode 5 on a developer carrying member 14 which carries developer by utilizing the synthetic rotary magnetic field of magnetic rolls 13A and 13B, and at least the surface of the part extending to the recording part of the electrode 15, which is the closest to the electrode 5, is formed of the magnetic material. Therefore, the magnetic flux in an area where the recording electrode is installed is focused on the recording electrode. Thus, the napping of the developer is orderly formed to have sufficient height en block on the recording electrode, and the high- resolution and high-density image is stably formed.

Abstract: PURPOSE:To stably form a high-resolution recorded image by forming a cylindrical electrode by laminating a surface layer consisting of a substance whose volume resistivity value is changed in accordance with the intensity of electric field on a conductive substrate. CONSTITUTION:The cylindrical electrode 5 is formed in two-layer structure obtained by laminating the surface layer on a conductive sleeve. The surface layer consists of the substance having characteristic that the volume electric resistivity value becomes smaller as the intensity of acting electric field gets higher. By arranging the electrode 5 so as to be opposed to a recording electrode 20, the line of electric force of the electric field by which developer (d) is transferred at an electrode opposing part is focused on the center part of the electrode. Thus, the developing electric field having the small radiation angle of the line of electric force and sharp intensity distribution is formed and the high-resolution image is stably formed with dots having proper size and distinct contour at the electrode opposing part where an enough opposing gap is secured.

Abstract: PURPOSE:To improve durability ad quality relating to noise reduction by disposing plural exciting coils along the inside surface of a non-magnet sleeve, energizing the exciting coils with alternating currents whose phases are properly shifted. CONSTITUTION:A coil roll R inserted ad firmly fixed in the sleeve 2 is constituted in such a manner that plural projecting parts 3a extend in parallel to one another along the axial direction at intervals around the surface of a base roll 3, and the coil 4 is formed by winding a conductor wire 4a around each projecting part 3a. The coils 4 are divided into groups having the same even number of coils, and the coils 4 of respective groups are uniformly distributed and arranged around the base roll 3. That is, in the case where the number of the coils of respective divided groups is (m), the identical coil 4 of the each group is arranged at every other (m-1) coils. A progressive wave magnetic field, which progresses along the periphery of the sleeve 2 is formed by energizing the coils 4 of the (m) groups with the alternating currents of (m) types, of (m) phases, whose phases are shifted by pi/m, in the order of arrangement, thereby carrying the magnetic powder dt. Thus, durability and quality relating to the noise reduction are improved.

Abstract: PROBLEM TO BE SOLVED: To provide a thermal transfer image forming device wherein toner is effectively melted by comparatively low energy of a printing head. SOLUTION: An image forming device carries a two-layers structure film 9 carrying toner and blank form by piling them up to an opposed part of a thermal head 7 and a platen. A current is selectively turned on to a heating element 7-1 to melt the toner 11 on the film 9, and a dot image is formed by selectively transferring to the sheet P. Respective heat conductivities λ1, λ2, and λ3 are so set as to increase successively in the order of a base 9a of the film 9, its carrier layer 9b, and the toner 11. Thereby, heat is transmitted by being concentrated in a reference position 7-1a direction from down to up (in sheet P surface direction from the heating element 7-1) more quickly than thermal diffusion in a lateral direction. The toner 11 in the reference position 7-1a direction is quickly melted by comparatively low heat energy, and transferred to the sheet P.

Abstract: PURPOSE:To provide a thermal transfer image forming device which is compact in size and low in cost, wherein a photosensitive body is not used specially, a toner is carried on a recyclable film, and images are printed on a paper by heating it with a thermal head. CONSTITUTION:A thermal head 2 having a number of heat generating bodies arranged in the vertical direction with respect to a paper face and a platen roller 3 are arranged in an opposed manner. Between them, a paper P superposed on a toner carrying film 4 is conveyed. The peripheral face of the toner carrying film 4 attracts a toner (t) by electrostatic force, while the heat generating bodies formed in the thermal head 2 are selectively energized. The energized heat generating bodies heat and melt the toner (t) at a corresponding part on the toner carrying film 4 and transfer on the paper P. By continuing the transferring process, toner images based on printing information are formed on the paper P.
