Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of image quality which is easily caused in toner recycling with small space at low cost by impressing bias for preventing toner from reversely flying on a member facing to the surface of an image carrier between a position after passing the developing area of a developing means and a position on this side of a transfer means. SOLUTION: In the case of recovering the residual toner by a photoreceptor cleaning device 200 and the cleaning means of a transfer belt device 600, the paper powder of transfer paper adheres to the surface of a photoreceptor 131 and the surface of a transfer belt 601, so that it is included in the recoverd toner to be reutilized. Then, the bias higher than the potential of a toner image on the photoreceptor 131 is impressed on a developing device lower case 309 being the member comparatively proximately opposed to the photoreceptor 131 between a downstream side from the developing area and this side of the transfer position. Thus, a situation that the paper powder and the toner reversely fly from the toner image on the photoreceptor 131 and are accumulated on the lower case 309 is restrained and the image from which the toner falls off is prevented.

Filed: 1978-03-23
Abstract: PURPOSE: To obtain complementary voltage-current converting characteristics accurately by connecting both emitters of first and second transistors to input terminal via resistance.  
     CONSTITUTION: When an AC voltage comes in to input terminal 1, the I 1  out of the output signals I 1 , I 2  drawn out after having undergone voltage-current conversion drives a power transistor Q 5  through a current mirror circuit consisting of transistors Q 5  and Q 4  and the I 2  directly drives the power transistor Q 6 . Then, the AC voltage having come in to the input terminal 1 is power amplified of its positive polarity component and negative polarity component by the power transistors Q 5 , Q 6  and is outputted from output terminal 3. At this time, the current value I 0  of idling current is of a small value and therefore a large current gain is obtainable.
