PURPOSE: To make the apparatus small in size, light in weight and convenient to carry by providing a condensing-type transmission body array in place of an in- mirror lens type optical system. CONSTITUTION: When a recording sheet 4 is inserted through a paper supply port 5, rolls 6a, 6b are revolved by the sheet detecting means disposed to paper supply rolls 6a, 6b, by which paper supplying is started. When the leading end of the sheet 4 is bited, DC high voltage is applied to the conductive rollers 6a, 6b, by which the sheet is electrically charged with electricity while being supplied simultaneously. When the leading end out the sheet 4 is bited into the conveying rolls 10a, 10b disposed just before a magnetic brush developing device 9, the paper supplying and the rolls are stopped by the sheet leading end detecting means disposed in this part, by which the sheet is placed still on a paper guide 11. After this, the latent image forming part formed with a condensing-type transmission body array 1 and a light source 3 into one body moves in the right direction to perform latent image formation. When this is completed, the sheet is sent to the developing device 9 by the rolls 10a, 10b, where it is applied with the magnetic toner 8 adsorbed on a magnet roll 12 and is thereby developed. After this, it is passed through a pair of rolls 13a, 13b, whereby it is press-stuck with the toners. COPYRIGHT: (C)1981,JPO&Japio
