An organic photoconductor including a base layer formed of a first material and a photoconductive layer formed of a second material. The organic photoconductor being characterized in that when it is maintained in a curved orientation with the photoconductive layer facing outward, the photoconductive layer is subjected to less stress than the base layer. In one embodiment the first material is relatively more flexible and stretchable than said second material and the materials are pre-stressed in opposite senses. In a second embodiment the first material is relatively flexible and stretchable and the second material is an initially less flexible and stretchable material which has been chemically treated to increase its stretchability and flexibility.

Organic photoconductor

Apparatus including a drum having a drum surface, apparatus for supplying a particle dispersion comprising particles to the drum surface, electrostatic apparatus for causing at least some of the particles to adhere to the drum surface and resilient blade apparatus downstream of the electrostatic apparatus for operative engagement with the drum surface for retaining a layer of particle rich material on the drum surface.
