摘要： PROBLEM TO BE SOLVED: To obtain an electrophotographic film to be transferred which is excellent in both of a traveling property and blocking property by providing the other surface of a transparent base with a back layer consisting of a conductive primer coating layer and a friction-coefft. decreasing layer. SOLUTION: The electrophotographic film to be transferred which is formed with an image receiving layer 12 on one surface of the transparent base 11 and is formed with the back layer 13 on another surface of the transparent bas 11 is illustrated. The back layer 13 consists of the conductive primer coating layer 14 and the friction-coefft. decreasing layer 15. The conductive primer coating layer 14 is formed on the transparent base 11 and the wear-coefft. decreasing layer 15 thereon. The conductive primer coating layer 14 bears the effect of suppressing the static electricity usually generated by the transportation of the electrophotographic film to be transferred within a copying machine and the effect of controlling the charges necessary for taner transfer. On the other hand, the friction-coefft. decreasing layer 15 acts to lower the friction coefft. of the electrophotographic films to be transferred with each other or with the transportation surface of the copying machine at the time of transportation.

摘要： PURPOSE:To improve adhesion property of toner picture images and embossing resistance by forming an image-receiving layer containing a polyester resin and chain-type colloidal silica and having specified surface resistance. CONSTITUTION:An image receiving layer 12 is formed on the surface of a transparent film 11. The image receiving layer 12 contains chain-type colloidal silica and polyester, and the colloidal silica is a dispersion liquid of fine particles of silica acid anhydride in water or an org. solvent such as alcohol. As for the colloidal silica, water-dispersion colloidal silica (silica sol) or org. solvent- dispersion colloidal silica is well-known. The fine particles of the water dispersion colloidal silica are stabilized with cation such as sodium ion. The org. solvent-dispersion colloidal silica is prepared by hydrophobidizing the surface of particles with hydroxyl groups and dispersing the particles in an org. solvent. The image receiving layer 12 has 1X10 -1X10 OMEGA (at 25 deg.C 65% RH) surface electric resistance. If the resistance is less than 1X10 OMEGA, the obtd. toner image has low density, and if the resistance exceeds 1X10 OMEGA, dust easily deposits.

摘要： PROBLEM TO BE SOLVED: To prevent peeling of a toner image formed in an image accepting layer and to prevent or largely decrease offset development on a fixing roll by forming a base coating layer of a hardened resin between the image accepting layer and a transparent supporting body. SOLUTION: A base coating layer 13 is formed on one surface of a transparent supporting body and further an image accepting layer 12 is formed thereon. The base coating layer 13 consists of a hardened resin. The resin consists of a copolymer containing 10 to 90wt.% diolefin monomers and 90 to 10wt.% vinyl monomers. The resin is preferably hardened by 2,4-dichloro-6-hydroxy-1,3,5- triazine deriv. The coating layer 13 has an effect to improve adhesion between the image accepting layer 12 and the base body 11 and an effect to improve adhesion of a toner. Thereby, offset development which means transfer of a toner or a toner with the image accepting layer 12 to a fixing roll in a toner fixing process is hardly caused.

摘要： PROBLEM TO BE SOLVED: To provide an electrophotographic image forming method capable of effectively suppressing surface charging cause by peeling between a belt surface layer and the image receiving layer of an image receiving sheet for electrophotography in a cooling/ peeling part thereby preventing dust from being attracted to the charges on respective surfaces and printing and outputting the images of high image quality close to photographic image quality. SOLUTION: The electrophotographic image forming method for fixing the image receiving sheet for the electrophotography by using a belt fixation type smoothing processing apparatus of a cooling/ peeling type having a cooling device and the cooling/ peeling part, is characterized in that surface electric resistance (SR1) on the image forming side of the image receiving sheet for the electrophotography is 1.0×10 9 Ω/cm 2 ≤SR1≤1.0×10 14 Ω/cm 2 and the surface electric resistance (SR2) on the image contact surface side of a belt in the belt fixation type smoothing processing apparatus of the cool peeling type is SR2≤1.0×10 14 Ω/cm 2 .
