Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of density fluctuation caused by an AC component in the case of executing developing by developing bias voltage obtained by superposing the AC component on a DC component. SOLUTION: The developing bias voltage obtained by superposing the AC component on the DC component by a power source 56 is applied to the sleeve 32B of a developing roller 32. The developing bias voltage is inputted to an arithmetic unit 62 as a bias signal when voltage division is executed by a potential divider 58 and a phase is changed by a phase adjusting unit 60. A video signal inputted by a video signal preparing unit 64 is corrected and outputted by the arithmetic unit 62 so as to increase outgoing light quantity from an LD 18 as the level of the bias signal is lowered and to reduce the outgoing light quantity as the level is raised. Phase changing quantity by the phase adjusting unit 60 is previously adjusted so as not to cause banding on a half tone image.  Thus, a developing electric field is set constant in spite of the periodical fluctuation of the developing bias voltage caused by the AC component, so that the occurrence of the banding is suppressed.

Filed: 1989-12-27
Abstract: PURPOSE:To obtain a wide dynamic range while keeping a high efficiency by controlling the drain voltage of an amplifier in response to the envelope level of an input signal, and compensating distortion with a distortion compensation circuit. CONSTITUTION:A nonlinear control circuit 20 varies a drain voltage in response to the envelope level of an input signal at a region where an input amplitude is large to correct the amplitude distortion of an amplifier 10, thereby enabling the operation of a class F amplifier with high efficiency and a large distortion, and fixes the drain voltage in a region where the input amplitude is small outside of a variably controllable range of drain voltages. Thus, the input - output characteristic of the amplifier is not linear. The characteristic of a polygonal line is compensated by a distortion compensation circuit 40 to attain the characteristic without distortion over a wide range. Moreover, the phase characteristic is made flat by using the distortion compensation circuit 40 to prevent the deterioration in a spectrum caused by phase distortion.
