Abstract
The organic photoreceptor includes a conductive support, an organic photosensitive layer, and a surface layer made of a cured resin, which are stacked in this order. The surface layer is obtained by curing a composition containing a radical polymerizable compound for forming the cured resin, metal oxide fine particles having a surface treated with a silane coupling agent, and a silane compound represented by the following general formula (1), wherein R1 to R3 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms, and at least one of R1 to R3 represents an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms.
Claims6
An organic photoreceptor comprising a conductive support, an organic photosensitive layer, and a surface layer made of a cured resin, which are stacked in this order
- wherein the surface layer is obtained by curing a composition containing a radical polymerizable compound for forming the cured resin, metal oxide fine particles having a surface treated with a silane coupling agent, and a silane compound represented by the following general formula (1),
- wherein R1 to R3 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms, and at least one of R1 to R3 represents an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms.
A production process of an organic photoreceptor, the organic photoreceptor including a conductive support, an organic photosensitive layer, and a surface layer made of a cured resin, which are stacked in this order, the process comprising:
- applying a composition containing a radical polymerizable compound for forming the cured resin, metal oxide fine particles having a surface treated with a silane coupling agent, and a silane compound represented by the following general formula (1), to the organic photosensitive layer formed on the conductive support to form a coating film;
- and
- curing the coating film to form the surface layer,
- wherein R1 to R3 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms, and at least one of R1 to R3 represents an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms.
