Inventor: SATO KOJI
IPC: G03G13/28
Filed: 1988-03-10
Abstract: PURPOSE:To obtain an excellent planographic printing plate which decreases generation of scumming by subjecting the hydrophilic radical polymerizable compd. in contact with the surface of an electrophotographic sensitive layer to radical polymn. by chemically active ray irradiation, thereby forming a hydrophilic surface layer on the surface of the photosensitive layer. CONSTITUTION:A base 1 having electrical conductivity and water resistance as well as the hydrophilic surface layer 3 formed by polymn of the hydrophilic radical polymerizable compd. on the electrophotographic sensitive layer 2 which is formed on the surface of said base 1 and contains the mixture composed of an org. photoconductive material and a resin binder as the essential component are provided. The use of the printing plate material as it is after formation of a toner image thereon without subjecting the material specifically to impartation of a hydrophilic property thereto is thereby enabled.

Title: Electrostatic recorder controlling method
Inventor: SAKURAI ISAO
IPC: G03G21/00
Filed: 1981-04-15
Abstract: PURPOSE:To reduce frequency of stops of recording operations in order to enhance operation efficiency, by deciding to continue or to stop recording operation depending upon the positions where coneyance of a recording paper fails. CONSTITUTION:When feed of a recording paper P by a paper roller 25 fails or an amount of feed is insufficient, a loop detector M1 does not act, so paper jam in the paper feeder is detected. An operator is informed of occurrence of the paper jam, and recording action is stopped. When an image-transferred recording paper is not separated from a rotary drum 20 with a separating electrode 22, it is forced to be separated with a fixed separating member 23. A mis-separation detector M2 detects this, and the paper forcibly separated is taken out into an auxiliary tray 32, thus permitting recording action not to be stopped when mis- separation occurs, so frequency of stops of recording operations to be reduced, and operation efficiency to be enhanced.
