Latest Patents
One of Toshiharu Doi's key patents is titled "Image recording apparatus with exposure start and toner supply control." This invention includes a photosensitive drum where an electrostatic latent image is formed through laser beam irradiation from an optical unit. The apparatus features a developing unit that receives toner from a toner feeder and is equipped with a toner agitator. This unit supplies toner onto the drum, converting the latent image into a visible one. A toner sensor is integrated to detect the concentration of toner within the developing unit, providing a corresponding detection signal. The toner supply controller manages the toner feeder by comparing the sensor's output with a varying standard voltage that changes linearly from a peak to a steady level. Additionally, the exposure start controller initiates the optical unit's irradiation of the photosensitive drum after the drum's rotation stabilizes but before the toner sensor's output reaches its peak level. Toshiharu Doi holds 1 patent for this innovative technology.
