Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2023024117
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that can increase the analog harmony characteristics by a high line number half tone while maintaining a high-quality digital harmony property.SOLUTION: In a graph with a vertical axis I and a horizontal axis V obtained by an EV curve measurement technique, when the V, when I is 0.500[μJ/cm2], is Vr[V], the maximum value of S[V.μJ/cm2] expressed by S=I.(V-Vr), when I is in the range of 0.000 to 0.030[μJ/cm2], is Smax[V.μJ/cm2], and the product of the light amount Ii[μJ/cm2] in the horizontal axis and the potential Vi[V] in the vertical axis, Si is Ii.(Vi-Vr)[V.μJ/cm2] in the intersection between the approximation straight line when I is in the range of 0.000 to 0.010[μJ/cm2] and the approximation straight line when I is in the range of 0.490 to 0.500[μJ/cm2], the electrophotographic photoreceptor satisfies the relation AR≤0.10, the AR being the ratio of Si and Smax.SELECTED DRAWING: Figure 6
