Patent JP-S59214826-A (JP)
Title: Optical deflector
Inventor: MIKAMI KAZUO
IPC: G02F1/29
Filed: 1983-05-20
Abstract: PURPOSE:To obtain a large number of resolution points by arranging adjacent electrooptic crystals to which a light beam to be deflected is incident symmetrically about a plane, and applying potentials having the opposite polarities to adjacent electrodes among four arcuate electrodes in the opposite directions. CONSTITUTION:When a platelike light beam G which is polarized F in an Z-axis direction and wide in an X-axis direction is made incident to an end surface 21a of the electrooptic crystal 21 of an optical deflector, an electric field EZ in the Z-axis direction of the electrooptic crystal 21 is distributed while varying in intensity linearly in the X-axis direction, so the light in the electrooptic crystal 21 is deflected to a constant extent with an electric field gradient in the X-axis direction. Consequently, projection light H is deflected to left or right. This light beam is converged by using a cylindrical and a concaved lens into a spot, and consequently deflection to specific width is performed regardless of the deflection position, so analog optical deflection with a high number of resolution points is attained. When the distribution of the electric field EZ is linear, the electric field gradient is constant at any place.

Title: Image forming device
Inventor: YOSHIDA TOMOSHI
IPC: G03G21/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To steadily form a toner image of high image quality for a long time by variably controlling, according to a print rate, a speed at which a toner carrier carries toner to a latent image carrier. SOLUTION: A drive-roll driving device 108 controls the rotating speed of a developing roll in three gradations, A, B and C. For example, it detects the print rates of print information by classifying it in three gradations that are less than 6%, 6% to less than 11%, and 11% and more, and sets the rotating speeds A, B and C of the developing roll so that they match the development of electrostatic latent images of the respective print rates classified in the three gradations.  Under such drive control, the developing roll is driven at a low rotating speed A [rotating speed (S/D) ratio 1.3] in the case of a print rate of less than 6%, driven at a medium rotating speed B (S/D ratio 1.5-1.6) in the case of 60% to less than 11%, and driven at a high rotating speed C (S/D ratio 1.8) in the case of 11% or more, thereby achieving high image quality print while maintaining the long life characteristics of the device.
