<p>PROBLEM TO BE SOLVED: To provide an electrophotographic device capable of improving the durable life of a discharge exposure light source by reducing the discharge exposure light amount, reducing the ozone amount by reducing a primarily electrifying current and improving the durable life of an electrifying device with a simple constitution and at a low cost. SOLUTION: In this electrophotographic device, which is provided with a photoreceptor 1 having a photosensitive layer consisting essentially of amorphous silicon and which successively repeats electrification, exposure, development, transfer and cleaning by rotating the photoreceptor 1, a discharge exposure area for erasing the exposure history of the photoreceptor 1 is provided on a downstream side in the rotating direction from an area for performing the transfer and on an upstream side in the rotating direction from an area for performing the cleaning and a toner included in a developer for performing the development is made spherical particles whose oblateness is >=1.0 and <1.4.</p> |
