摘要： Systems and methods are described that facilitate eliminating a need for a raster output scanner (ROS) or laser when generating a latent image on a photoreceptor. An addressable backplane is employed, comprising an array of field effect transistors (e.g., silicon or organic thin film transistors, or TFTs), wherein each TFT corresponds to a single pixel on a charge transport layer on the photoreceptor surface. Latent image formation is performed by forming a surface potential using corona charging, and then directing free charge carriers toward the photoreceptor surface to reduce electrostatic potential in areas that need to be toned. TFTs in the array are individually addressed, or selected, to connect to a common ground, which allows photodischarge to occur only in selected areas (e.g., pixels associated with the selected TFTs). Once the array of TFTs is addressed, an LED light source emits light over the surface of the photoreceptor, and only the selected (grounded) TFTs permit their associated pixels to discharge. In this manner, a latent image is formed without a need for a bulky and expensive ROS.

摘要： An optical output level of laser diodes is detected by a photodiode for each of the laser diodes, and this photodiode detection output is used in feedback control of the laser diodes, thereby achieving stabilization of the optical output levels of the laser diodes. Furthermore, feedback control gain and laser diode bias are stored in an EEPROM (nonvolatile memory), and the feedback control is carried out according to arithmetic processing by an integrated circuit using the gain and bias in the EEPROM such that malfunctions of the optical scanning device can be addressed by rewriting the gain and bias in the EEPROM.

摘要： A two-dimensional array include N light-emitting arrays each formed of M light-emitting units arranged equally spaced along a direction T tilting from a main scanning direction at an angle α toward a sub-scanning direction. The light-emitting arrays are equally spaced in the sub-scanning direction. A space ds2 between light-emitting arrays with respect to the sub-scanning direction satisfies ds2=ds1×M where ds1 is a positional difference in the sub-scanning direction between light-emitting units which are adjacent each other in the main scanning direction and orthographically-projected on a virtual line extending in the sub-scanning direction. The angle α satisfies α=sin−1((ds2/d1)/M) where d1 is a space between light-emitting units in the light-emitting array with respect to the direction T. The space ds2 is equal to the space d1.
