摘要： PURPOSE: To prevent charge unevenness caused by a carrier liquid and to output a high quality image over a long time by providing a means drying the carrier liquid remaining on the surface of a photoreceptor after being cleaned. CONSTITUTION: A hot air type dryer 20 for drying the carrier liquid remaining on the drum type photoreceptor 1 after being cleaned is arranged around the photoreceptor 1 rotated in the direction of the arrow A. The hot air type dryer 20 blows hot air heated by a heater to the surface of the photoreceptor 1 in the direction of the arrow C, to dry the photoreceptor 1 and air contg. carrier liquid vapor after drying is sucked and removed in the direction of the arrow D. The air contg. the carrier liquid vapor passes through a filter and the carrier liquid is recovered by the filter. Moreover, in the hot air type dryer 20, the hot air flows on the photoreceptor in the direction opposite to the rotational direction A of the photoreceptor 1, so that the hot air contg. the carrier liquid vapor does not reach a charger 8.

摘要： PURPOSE:To provide high quality color images without color slippage by carrying a recording medium carrier means to a transfer position at least at the time of transfer and letting a carrier period be, the integer multiple of the scanning period of the scanning starting signals of beams. CONSTITUTION:A transfer drum 6 is provided on the periphery of a photosensitive body 1 and toner images are transferred to recording paper 7 held by the drum 6 at a transfer point by a transfer device 8. Thus, the transfer device 8 is carried to the transfer position at least at the time of the transfer. Then, a reference clock is frequency divided into appropriate frequency and a polygon mirror driving motor 11 and a transfer body driving motor 14 are driven so as to eliminate the deviation of a frequency pulse and a pulse from a motor encoder. In this case, since the motors 11 and 14 are pulse motors, a rotating speed can be changed by the waveform of the pulse and the rotating period of the transfer device can be the integer multiple of the period of the scanning starting signals. Thus, the dispersion among laser writing positions for each color is eliminated and the high quality color images without the color slippage can be obtained.

摘要： PURPOSE:To stably form a toner layer on a developer carrier for a long time by projecting and attaching a soft elastic body, which is placed on a pressing and contacting part between a supporting body having a specific spring plate and the developer carrier from the tip part of the supporting body to a toner amount regulating member. CONSTITUTION:The toner amount regulating member 7 consists of the supporting body 7a having the spring plate with >= 15kg f/mm tensile strength and >= 10kg f/mm bearing force, and the soft elastic body 7b placed on the pressing and contacting part between the supporting body 7a and the developer carrier 6 on the supporting body. In addition, the soft elastic body 7b is projected from the tip of the supporting body 7a to be attached. Thus, contact pressure of the toner amount regulating member 7 to the developer carrier 6 can be decreased drastically; moreover, the tip of the soft elastic member 7b is uniformly pressed in the axis direction and the peripheral direction on the developer carrier even when the toner amount regulating member 7 comes into contact with the developer carrier 6 with low pressure. Therefore, an image of a uniform and stable toner amount can be formed on the developer carrier.

摘要： PURPOSE:To manufacture the rotary particles for display at low cost by grinding plate body consisting of two layers which differ in color and electrostatic charging characteristics in dielectric liquid and have a specific layer thickness ratio, and performing a hot blast treatment and classification and thus obtaining specific Wadell practical spheroidicity and specific particle size. CONSTITUTION:Sheets of a kneaded body 1a of styrene acryl copolymer resin and white titanium oxide and a kneaded body 1b of said resin and black carbon black are put one over the other and run through a rolling machine while heated to form a laminate sheet which has a 20:1-1:20 layer thickness ratio and an about 50mum overall thickness. The laminate sheet after being cooled is ground by a turbo type grinding machine and the hot blast treatment of 300 deg.C and classification are carried out to obtain particles of 5-3,000mum in mean particle size and 0.7-1.0psim in Wadell practical spheroidicity. The particles are dispersed in two-liquid silicone rubber 2, heated and cured in a plate shape, and further dipped in silicone oil 4 and swelled, and thus the particles are suspended in the oil; and electrodes 6 are brought into contact with the top and reverse surfaces to obtain a display device.
