Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a very high-quality image having no defect caused by charge injecting property such as a positive ghost or a black stripe on a half tone image by incorporating a specified charge transport material in the surface layer of a photoreceptor and containing conductive electrification accelerating particles on an electrifying member so that injection electrification may be performed on the surface of the photoreceptor. SOLUTION: In a state where the conductive electrification accelerating particles exist on the mutual contact surfaces of the surface of the electrophotographic photoreceptor whose surface layer incorporates one or more kinds of charge transport material consisting of a specified amine compound shown by an expression and the contact electrifying member, the electrophotographic photoreceptor is contact-electrified. It is desirable that the electrification accelerating particles exist with such density as >=102 number/mm2, and the electrifying member contact-electrifies the electrophotographic photoreceptor in a state where it is brought into contact with the electrophotographic photoreceptor with the difference of circumferential speed. In the expression, Ar1 to Ar3 show an allyl group which may have a substitutional group.  It is good that Ar1 and Ar2 form a ring directly or through other organic residue such as -CH2- or -O-.

Title: Special image device
Inventor: ABE MASAHIRO
IPC: H04N9/74
Filed: 1987-10-07
Abstract: PURPOSE:To display a small display screen without shifting the hue by taking correlation with the polarity of a chrominance signal and executing sampling when a video signal of a system where the polarity of a video chrominance signal is changed and transmitted at every H line is displayed as the small display screen. CONSTITUTION:The chrominance signal is inputted to a chrominance signal polarity discrimination circuit 31 and the output of that is inputted to a sampling control gate 33. When a small screen which is 1/n (n: even number) of the whole screen is displayed, the output of the circuit 31 is inputted to a sampling control gate 34 by switching a change-over switch 32 to a negative side and a chrominance signal sampling signal 14 is controlled. Besides, when a small screen which is 1/n (n: odd number) of the whole screen is displayed, the chrominance signal sampling signal 14 is not controlled by the output of the circuit 31 by switching the change-over switch 32 to a positive side. Thus, the hue shift of the small display screen of one even-number-th is fixed and the small screen of one odd-number-th can be displayed without shifting the hue.
