PURPOSE:To make it possible to surely prevent toner from scattering due to the wind or the like or sticking to hands or clothes by a construction wherein a heating means for half-fixation of a toner image is provided in the vicinity of a developer which feeds the toner. CONSTITUTION:In opposition to an electrostatic recording medium 1, a recording head 6 constructed of an element 4 of a writing electrode, i.e. a stylus electrode, and an element 5 of a control electrode, an AC deelectrifier 7, a cleaning blade 8, a CCD line sensor 10 equipped with a lens system 9, and a reflector mirror 11, are disposed, and a developer 12 which toner feeds is also provided. In the vicinity of the developer 12, a xenon lamp 21 as a heating means, which extends in the direction of the width with substantially the same dimension with that in the direction of the width of the electrostatic recording medium 1, is provided. This xenon lamp 21 gives by flashing an energy of about 1/3 of the one for complete fixation, i.e. 0.5 to 0.7 joule/cm , to toner 16b of styrene- acryl from the developer 12, so that a toner image can be half-fixed.

PURPOSE:To facilitate the display of a list and a graph by providing a memory storing original information to a supply means of the original information, supplying the original information stored in the memory to an electrostatic recording head and displaying the information on an electrostatic recording sheet. CONSTITUTION:When a character or a list or the like drawn on an original is stored in a memory 22, at first a mode changeover switch 31 is thrown to the position of the pattern mode. Then the original desired to be stored is loaded to an original insertion port of the electronic blackboard and a storage switch 37 is depressed. Thus, the loaded original is read by an original read section 23. The original information is stored as a pattern in the write area of the memory 22. Then in case of displaying the pattern stored in the memory 22 on the sheet 1, at first, the mode changeover switch 31 is thrown to the position of the pattern mode and either of setting pattern selector switches 32-35 or a storage pattern selector switch 36 is depressed to select which pattern picture is to be displayed.

PURPOSE:To avoid ghost phenomenon and to improve the grade of the quality of displayed picture image by constituting an electroconductive layer of an anisotropic electroconductive layer having a resistance in a direction of arrangement of plural writing styli held higher than the resistance in the orthogonal direction to said direction of the arrangement. CONSTITUTION:A dielectric layer 23 charged by a recording head 4 by being faced opposing to an electroconductive layer 22 and styli is provided to a recording medium 20, and the electroconductive layer 22 is constituted of an anisotropic electroconductive layer having a resistance in a direction (x) of the arrangement of plural wiring styli held at a higher resistance than the resistance in the direction (y) orthogonal to the direction of the arrangement. Thus, a space between a selected control electrode and a stylus electrode is brought to a conductive state in the direction of relatively low resistance value of the electroconductive layer 22, in the writing stage of an electrostatic latent image onto the medium 20, permitting thus satisfactory writing. The influence of the electric voltage of the selected stylus electrode is shielded by the electroconductive layer 22 in the direction (x) which obtains a high resistance value in the direction of arrangement of the styli, so generation of ghost phenonmenon is avoided, and the grade of the quality of displayed picture image is improved.

PURPOSE:To form a small-sized, diverse liquid crystal device by installing a photodetecting element between transparent bases, driving a liquid crystal device, and putting the liquid crystal device in operation as a printer and further an image scanner in addition to a liquid crystal shutter. CONSTITUTION:The device 1 receives original reflected light passed through a convergent rod array lens 13 by the photodetecting element 7 of the device 1 and operates liquid crystal 6 as a liquid crystal shutter between the transparent electrodes 4 and 5 to obtain a desired copy image by the electrophotographic means composed of a photosensitive drum 21 arranged under the device 1. Then, image signals are converted into electric signals simultaneously or individually because of characteristics of liquid crystal and outputted to a memory device through a CPU to make the device function as the image scanner. Further, the device 1 is driven as the liquid crystal shutter which operates on the basis of external or internal image signals to obtain the functions of the printer based upon the electric signals.
