摘要:
Disclosed herein is a photoreceptor for electrophotography (10) having an over coating layer (14) formed on a substrate (11) and prepared by applying a composition containing silica particles, an organic compound chemically bonded thereto and a photo polymerization initiator and by curing said composition; said organic compound having an polymerizable unsaturated group, a group designated by Formula (1) or a group designated by Formula (2), and said silica particles and said organic compound being bonded with each other through a silyloxy group. The photoreceptor for electrophotography (10) has not only excellent durabilities and an excellent resistance to printing but also excellent electrophoto characteristics such as sensitivity and a residual potential. (wherein -X- is selected from -NH-, -O- and -S-, -Y- is an oxygen atom or a sulfur atom, and when -X-is -O-, Y is said sulfur atom)
摘要:
A photoconductive recording material containing a support and a charge generating layer (CGL) in contiguous relationship (contact) with a charge transporting layer (CTL), containing an n-charge transporting material (n-CTM), wherein the binder of said charge generating layer (CGL) is made insoluble in methylene chloride by cross-linking, and said binder is composed essentially of one or more polyepoxy compounds self-cross-linked under the influence of an amine catalyst and/or cross-linked by reaction with at least one primary and/or secondary poly NH-group amine.
摘要:
An electrophotographic photosensitive member comprising a conductive support, a photosensitive layer and a protective layer containing a setting resin, characterised in that the photosensitive layer contains a resin which has a glass transition point of 170°C or more. The above image forming apparatus has excellent durability and good image forming properties.
摘要:
An electrophotographic apparatus is disclosed which has an electrophotographic photosensitive member and a transfer means. The photosensitive member has a conductive support and a photosensitive layer, and further has a surface layer comprised of a binder resin, fluorine atom- or silicon atom-containing compound particles incompatible with the binder resin, and a fluorine atom- or silicon atom-containing compound compatible with the binder resin. In the surface layer, the proportion of fluorine atoms and silicon atoms to carbon atoms, (F+Si)/C, as measured by X-ray photoelectron spectroscopy is 0.01 to 1.0. Additionally, the transfer means is a multiple-transfer means.
摘要:
A photoconductive recording material comprising a support and a charge generating layer (CGL) in contiguous relationship with a charge transporting layer (CTL) containing a p-charge transporting material (p-CTM), wherein the binder of said charge generating layer (CGL) has been made insoluble in methylene chloride by crosslinking, and said binder is composed essentially of at least one epoxy resin (1) as defined herein and/or at least one dialkanolamine-modified epoxy resin linked with at least one polyisocyanate.
