Latest Patents

Matsuo's latest patents include innovative technologies aimed at improving electrophotographic devices. One of his notable inventions is a method for laser beam emission control, which regulates laser power at two predetermined points of gradation. This method includes a first laser power regulating means that controls the magnitude of the laser power output and a second means that regulates the slope of the laser power gradation characteristic. This innovation stabilizes the laser power output value at any stage of gradation, thereby reducing variability in image quality across different electrophotographic devices.

Another significant patent is for an electrophotographic image forming apparatus designed to restrict or eliminate density fluctuations, such as lateral stripes, which can detract from image quality. This apparatus features a photosensitive body, an exposure device for creating an electrostatic latent image, and at least two developers for developing the electrostatic image in distinct colors. It also includes a transfer device for overlapping toner images on a printing medium and a fixing device for securing the transferred images. Notably, when one of the developers is inactive, it can be forced into operation for a reset.
