The present invention relates to a material for a charge transport layer of an organic electrophotographic photoreceptor having a photosensitive layer laminated in this order.
近年、電子写真方式の複写機、プリンタなどに用いられ
る電子写真用感光体の感光材料として、有機光導電性物
質の研究が広く進められている。In recent years, research on organic photoconductive substances has been widely advanced as photosensitive materials for electrophotographic photoreceptors used in electrophotographic copying machines, printers, and the like.

去、光除電などを行った後、再使用に供される。In electrophotographic copying machines, printers, etc., the curling method is generally applied. This method of image formation involves charging the photoconductor in a dark place by corona discharge, forming electrostatic latent images such as letters and pictures by exposing the charged photoconductor surface to light, and discharging the formed electrostatic latent image. This is done by developing with toner, transferring the developed toner image to a support such as paper, and fixing it.After the toner image has been transferred, the photoreceptor is subjected to static electricity removal, residual toner removal, photostatic static removal, etc., and then it can be reused.

It has excellent electrical and photoelectric properties such as repeated characteristic stability, as well as mechanical strength (hardness, abrasion resistance, etc.).
It must also have excellent environmental stability (heat resistance, moisture resistance, resistance to light and ozone, etc.).

に問題を有していた。Photosensitive materials using organic photoconductive substances have greater flexibility, thermal stability, film-forming properties, transparency, and material properties compared to conventionally used inorganic photoconductive substances such as selenium. Although it has many advantages such as versatility and low price, it has problems such as photosensitivity, stability of repeated characteristics, abrasion resistance, and durability against light and ozone.

ことから現在主流となっている。Therefore, by taking advantage of the diversity of materials and film-forming properties, the photosensitive layer of the photoreceptor is divided into a charge generation layer that contains a charge generation substance and mainly contributes to charge generation during light reception, and a charge generation layer that contains a charge transport substance and mainly contributes to the generation of charges during light reception. The photoreceptor as a whole is made up of a stack of functionally separated layers, including a charge transport layer that contributes to the retention of surface charge at the surface and charge transport during light reception, and by selecting and using materials suitable for the functions of each layer. Organic photoreceptors are being put into practical use with improved characteristics. Among these, negatively charged type laminated photoreceptors in which a charge generation layer and a charge transport layer are successively laminated on a conductive substrate are currently mainstream because they are advantageous in terms of abrasion resistance and durability.
