Abstract
A process unit includes a photoreceptor drum, a frame and seal members. The photoreceptor drum has drum flanges protruded outwardly from both end surfaces of a substrate. The frame supports the photoreceptor drum rotatably. The seal members are provided between both end surfaces of the photoreceptor drum and the frame, and support the drum flanges. Each of the seal members includes an elastic member and a hard member. The elastic member and the hard member are adhered and laminated with each other in an axial direction of the photoreceptor drum. Furthermore, the hard member is arranged so as to be brought into contact with the photoreceptor drum.
Claims8
A process unit, comprising
- an electrostatic latent image bearing member having flanges protruded from both end surfaces of a substrate that is formed in a cylinder shape;
- a frame that supports the electrostatic latent image bearing member rotatably;
- and
- seal members provided between both end surfaces of the electrostatic latent image bearing member and the frame, the seal members holding the electrostatic latent image bearing member concerned by supporting the flange, each of the seal members being formed by laminating a first member that is brought into contact with the electrostatic latent image bearing member and a second member that is made from a material different from a material of the first member and brought into contact with the frame.
