<p>PROBLEM TO BE SOLVED: To provide an electrophotographic cartridge configured to prevent cracks as well as filming, even when a large amount of silica particles are added to obtain filming effect, and an electrophotographic photoreceptor, and an image forming apparatus.SOLUTION: An electrophotographic cartridge includes an electrophotographic photoreceptor, charging means, image exposure means which performs image exposure to form an electrostatic latent image, and developing means which develops the electrostatic latent image with toner. The charging means is contact roller charging. The electrophotographic photoreceptor includes a charge generating layer and a charge transport layer formed in this order on a conductive substrate. The charge transport layer is a single layer and an outermost surface layer, and includes a charge transport material, a binder resin having a repeated structure unit with a molecular weight of 210-290, and silica particles having an average primary particle size of 0.1-1.5μm. The content of the silica particles in the charge transport layer is 3-20wt%.</p> |
