Title: Mihoko Okada: Innovator in Image Forming Technology

Introduction

Mihoko Okada is a prominent inventor based in Yamatokoriyama, Japan. She has made significant contributions to the field of image forming technology, holding 2 patents that enhance the performance and quality of devices such as copying machines and laser printers.

Latest Patents

One of her latest patents is an "Image forming device with residual charge removal control." This invention relates to image forming devices that utilize an electrophotographic process. It introduces a simple control method that does not require complex means to equalize the surface potential of a light-sensitive drum. This innovation ensures high-quality images even during the first rotation of the drum. The device includes a charge-removal prohibiting means, a charge-potential changing means, and a developing bias-potential changing means, all controlled based on the surface potential changes influenced by light fatigue and ambient temperature.

Another notable patent is the "Image forming apparatus having an image-quality correction function." This apparatus compensates for voltage applied to an exposure lamp and charger based on changes in toner image density. A toner-density sensor measures the density of a reference toner image, and a subtracter calculates the amount of change from its initial state. The system uses a neurocomputer to learn the relationship between density change and voltage compensation, ensuring stable image quality and reducing the number of parts required in image forming apparatuses.
