Abstract
An apparatus for forming an image that can stably provide an image for a long period of time is provided by using an electrophotographic photoreceptor having, as the outermost layer, a hard film containing one or more of a charge transporting organic silicon compound. It is an apparatus for forming an image containing a photoreceptor having, as an outermost layer, a hard film containing one or more of a charge transporting organic silicon compound represented by the following general formula (I), the outermost layer having a wear rate of about from 5 to 30 nm per 1,000 revolutions of the photoreceptor: F-[D-A]b (I)
Claims20
A method for regenerating an image forming apparatus comprising:
- abrading a photoreceptor having, as an outermost layer, a hard film formed by hydrolytic condensation and curing of a coating composition containing one or more charge transporting organic silicon compounds represented by the general formula (I):
- F-(D-A)b (I)
- wherein
- F represents an organic group derived from a charge transporting compound;
- D represents a flexible sub-unit;
- A represents a substituted silicon group having a hydrolytic group represented by —Si(R1)(3-a)Qa, wherein R1 represents hydrogen, an alkyl group or a substituted or unsubstituted aryl group, Q represents a hydrolytic group, and a represents an integer of from 1 to 3, and b represents an integer from 1 to 4, with an abrading device;
- and
- controlling the wear rate of the outermost layer.
A method for regenerating a process cartridge comprising:
- abrading a photoreceptor having, as an outermost layer, a hard film formed by hydrolytic condensation and curing of a coating composition containing one or more of a charge transporting organic silicon compound represented by the general formula (I),
- F-(D-A)b (I)
- wherein
- F represents an organic group derived from a charge transporting compound;
- D represents a flexible sub-unit;
- A represents a substituted silicon group having a hydrolytic group represented by —Si(R1)(3-a)Qa, wherein R1 represents hydrogen, an alkyl group or a substituted or unsubstituted aryl group, Q represents a hydrolytic group, and a represents an integer of from 1 to 3, and b represents an integer from 1 to 4, with an abrading device;
- and
- controlling the wear rate of the outermost layer.
