Filed: 1988-06-02
Abstract: PURPOSE: To obtain an optical transducer satisfying performances including resolution, accuracy, and independent of some vibration by equipping a 1st measuring screen having parts 1 and 2 with different optical feature placed between a light source and a receiver and a 2nd measuring screen moving together with a writing head. CONSTITUTION: The slit pitch D1 of the 1st measuring screen 21 is larger than the slit pitch D2 of the 2nd measuring screen 22 The width B1 , B2 of light shielding part of each of screens 21, 22 is wider than the width A1 , A2 of transparent part. The distance L from the screen 21 to the plane where the shadows meet is calculated by an equation, L=D1/(D1-D2)×H, if the distance between the two screens is H. The shadow width W on the image plane is independent of the relative change of the position of the measuring screens parallel to the plane where they stand. The light receivers 13, 14, and 15 are placed on the image plane in the smaller allowance than the shadow width. The shadow meeting point maintains a stable lower brightness in spite of vibration of the screen 22.

Abstract: PURPOSE: To appropriately control the density by detecting the amount of toner adhering to the electrostatic latent image of a reference pattern in a specified timing and controlling the value of developing bias potential and the amount of toner supplied to a developing device. CONSTITUTION: When a photoreceptor drum 41 to which negative surface potential is given by an electrifying charger 43 is irradiated with a laser beam, the surface potential of an irradiated position is transited to decay potential. When the absolute value of the surface potential is lower than that of the developing bias potential given to the roller of the developing device 45 by a developing bias generating unit 244, the toner sticks to the drum 41. The amount of toner stuck to the electrostatic latent image of the reference pattern is detected in a specified timing by an AIDC sensor 210, and a printer control part 201 changes the value of the developing bias potential to be within a reference range in the case where the sticking amount is out of the reference range.  Then, the changed value of the bias potential is restored to a standard value stepwise, and the amount of toner supplied to the developing device is controlled so that the sticking amount of toner may be within a specified range.
