Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor providing a good image quality, and also to provide an electrophotographic apparatus using the electrophotographic photoreceptor.

SOLUTION: In the electrophotographic photoreceptor 11, a photosensitive layer 25 is formed by applying and drying a coating liquid prepared by dissolving a charge transfer agent represented by a formula (1) in tetrahydrofuran on a conductive support 21. Since even when tetrahydrofuran remains in the photosensitive layer 25, it does not affect the properties of the photosensitive layer 25, the photosensitive layer 25 can be formed by low-temperature short-time drying. The photosensitive layer 25 does not crack thereby, and the electrophotographic photoreceptor 11 having excellent quality is provided.

【課題】画像品質の良い電子写真感光体を提供する。
【解決手段】本発明の電子写真感光体11では、感光層25が、下記一般式(1)で示される電荷移動剤をテトラヒドロフランに溶解した塗布液を、導電性支持体21上に塗布乾燥して形成される。テトラヒドロフランは感光層25中に残留しても、感光層25の特性に影響を与えないので、低温、短時間の乾燥で感光層25を作成できる。従って、感光層25にはクラックが発生せず、品質に優れた電子写真感光体11が得られる。
