り、感度の劣化を防止する技術が開示されている。Generally, this type of electrophotographic photoreceptor is constructed by providing a photosensitive layer on a support made of aluminum, aluminum alloy, etc., either directly or via an intermediate layer, by vapor deposition, coating, or the like. Regarding the surface shape of the support, several regulations have been proposed so far. For example, JP-A-60-
No. 112049 discloses that the surface of the support is roughened, the roughened surface has flat groove-like unevenness, and the distance between the ridges is 20/2.
A technique is disclosed for improving the adhesion between the support and the photosensitive layer or intermediate layer by specifying that the peak height is 0.31a to 2. Also, JP-A-61-46
No. 966 describes the surface roughness of the support surface as O, OS,

42498, the maximum surface roughness of the support is 0.7.
A technique has been disclosed in which deterioration of sensitivity is prevented by setting the average surface roughness to 1 s or more and the average surface roughness to 0.5 or more.

同一のパターンで濃淡むらが生じるという欠点がある。However, with conventional electrophotographic photoreceptors constructed using supports based on the above-mentioned regulations, when images such as halftone images are produced, uneven shading occurs in the same pattern as the surface shape of the support. There is a disadvantage that it occurs.

In an electrophotographic photoreceptor used in an electrophotographic process lasting more than a second, the average surface roughness of the photoreceptor is 0.3-5.0-
(Japanese Unexamined Patent Publication No. 1-99060) and an electrophotographic photoreceptor in which the surface roughness of the r photosensitive layer is 172 or more of the light wavelength of the light source used for image formation at a ten-point average roughness Rz. ” (Japanese Unexamined Patent Publication No. 163058/1983) has been proposed. Although these electrophotographic photoreceptors have relatively eliminated the above-mentioned drawbacks, the former photoreceptor has the disadvantage of high cost because it is necessary to polish the surface of the photoreceptor in the running direction with a wrapping tape. Moreover, since the coating film of the latter photoreceptor is sandy and rough, toner powder tends to stick to the surface, resulting in so-called toner filming.
本発明は、上記従来技術の実情に鑑みなされたものであ

が防止でき、しかも低廉なコストで生産し得る電子写真
用感光体を提供することを目的とする。The present invention has been made in view of the above-mentioned state of the prior art, and an object of the present invention is to provide an electrophotographic photoreceptor that can prevent the occurrence of abnormal images such as moiré and toner filming, and can be produced at low cost. With the goal.
本発明者らは、上記課題を解決すべく鋭意検討した結果
、最大表面粗さ(Rffiax)0.3〜1.5μsで
ピッチ0.2〜2a+mのスパイラル状に塗布された感
光層を有する感光体が上記目的に適合することを見出し
た。As a result of intensive studies to solve the above problems, the present inventors discovered that a photosensitive layer having a photosensitive layer coated in a spiral shape with a maximum surface roughness (Rffiax) of 0.3 to 1.5 μs and a pitch of 0.2 to 2 a+m The body was found to be suitable for the above purpose.

子写真感光体が提供される。That is, according to the present invention, in an electrophotographic photoreceptor comprising a photosensitive layer provided on a support, the photosensitive layer has a maximum surface roughness (Rmax) of 0.3 to 1.54 and a pitch of 0.2 to 2 m.
Provided is an electrophotographic photoreceptor characterized in that the composition is coated in a spiral manner.
本発明の電子写真用感光体は前記構成からなるので、高
感度であると共にモアレ等の異常画像の発生がなく、ま
たトナーフィルミングを防止し得るものである。Since the electrophotographic photoreceptor of the present invention has the above-described structure, it has high sensitivity, does not generate abnormal images such as moiré, and can prevent toner filming.
感光層の最大表面粗さ(Rmax)が(1,3戸未満で
あると、モアレが発生し、また1、5.を超えるとトナ
ーフィルミングが発生するので好ましくない。If the maximum surface roughness (Rmax) of the photosensitive layer is less than 1.3, moire will occur, and if it exceeds 1.5, toner filming will occur, which is not preferable.
また、感光層が0.2〜2mm間隔にし、スパイラル状
に塗布されていないとクリーニング不良が発生し易くな
るため本発明の所期の目的を達成することができない。Furthermore, unless the photosensitive layers are coated in a spiral manner with an interval of 0.2 to 2 mm, cleaning failures tend to occur, making it impossible to achieve the intended purpose of the present invention.
