摘要： In an image forming apparatus, a resistant layer of each writing electrode is formed substantially in a semi-circular convex shape projecting upwardly. The top of the resistant layer is a spherical surface so that the resistant layer is in point contact with the charged layer of the latent image carrier. Because of point contacts, foreign matters adhering to the surface of the latent image carrier are easily allowed to pass, thereby preventing the occurrence of filming on the surface of the latent image carrier.

摘要： In an image forming apparatus of the present invention, a plurality of writing electrodes are supported by an elastic and flexible substrate such that the writing electrodes are aligned in a plurality of rows each extending in the axial direction of the latent image carrier (in the main scanning direction). The writing electrodes are each formed in, for example, a triangle and alternately inverted. In this case, one end of a writing electrode is overlapped with a next writing electrode, as seen in the direction perpendicular to the axial direction of the latent image carrier (the rotational direction of the latent image carrier; the feeding direction). Therefore, this design prevents occurrence of image defect due to linear stains and allows foreign matters adhering to the surface of the latent image carrier to pass through spaces between the adjacent writing electrodes.

摘要： Writing electrodes of a writing device are kept in contact with a latent image carrier with a small pressing force by a weak restoring force of a substrate. An electrostatic latent image is written on the latent image carrier by applying or removing charge relative to the latent image carrier which is already uniformly charged by a charge control device. The application or removal of charge is conducted via charge-transfer between the latent image carrier and the writing electrodes which are in contact with each other. The electrostatic latent image is developed by a developing device to form a developing powder image and this developing powder image is transferred to a receiving medium such as a paper by a transferring device. Since the writing electrodes are employed as the writing device, the apparatus can be manufactured smaller and simply and can steadily write an image.

摘要： An electrophotographic printer includes an exposure unit having a MEMS scanner operable to scan a beam of light across a photoconductor. The MEMS scanner includes a mirror having an aspect ratio similar to the shape of the facets of a conventional rotating polygon scanner. In a preferred embodiment, the scan mirror has a length of about 750 microns in a dimension parallel to its axis of rotation and a length of about 8 millimeters in a dimension perpendicular to its axis of rotation. The MEMS scanner is operable to scan at a frequency of about 5 KHz and an angular displacement of about 20 degrees zero-to-peak mechanical scan angle.
