Abstract
In an example, a photosensitive imaging surface is provided by an extended photodiode structure.
Claims14
A photosensitive imaging surface provided by an extended photodiode structure, the photosensitive imaging surface comprising a layer divided into pixels by barriers which act to block at least one of optical radiation transmission and charge transfer therethrough.
A method comprising:
- charging a surface of a photosensitive imaging device with charges originating within a photodiode structure on which the surface is formed, by applying an electric field to the photosensitive imaging device;
- and
- forming a charge pattern on the surface by selectively irradiating the surface.
A printing apparatus comprising:
- a photosensitive imaging surface provided by an extended photodiode structure;
- a charging element to apply an electric field to cause movement of charge towards a face of the photosensitive imaging surface;
- and
- a write head, to selectively discharge a portion of the photosensitive imaging surface.
