成装置。 A photosensitive drum used in copying machines, printers, facsimiles, etc. that record by electrophotography, an electrostatic latent image forming means for forming an electrostatic latent image on the photosensitive drum, the photosensitive drum and the electrostatic latent image. In order to keep the forming means at regular intervals, in an electrostatic latent image forming apparatus consisting of a positioning member, one of which is attached to the electrostatic latent image forming means and the other is in contact with the photosensitive drum, the positioning member is molded of resin or the like. An electrostatic latent image forming device, characterized in that the electrostatic latent image forming device is manufactured by the above method, and a curved surface having a radius of curvature that is the same as the radius of the photoconductor is formed on a part of the surface that contacts the photoconductor drum.
