    Abstract: A method for forming a color image includes a step of spraying three kinds of photoconductive toners with a sensitization wavelength band different from its absorption wavelength band, a step of electrically charging these different toners, a step of exposing these sprayed and electrically charged photoconductive toners to light for selectively removing electrostatic charges, and a step of removing the toners freed of electrostatic charges from the substrate. The magenta color photoconductive toners sensitive to red light, yellow color photoconductive toners sensitive to green light, and the cyan color photoconductive toners sensitive to blue light, are used as aforementioned three kinds of photoconductive colors.

    Abstract: A spectrophotometer of the type using a pulse motor to rotate a diffraction grating through a speed reducing mechanism has a capability of constructing a conversion table according to a program, by which table a rotation amount of the motor is converted to a corresponding wavelength of output light from a monochromator. The spectrophotometer is capable of designating a calibration mode in which an emission peak at a known wavelength of light from a light source is detected, a coefficient in a conversion equation is determined on the basis of the known wavelength of the emission peak and a rotation amount of the motor at a time when the emission peak is detected, and the determined coefficient is used to construct the conversion table which is then stored in a nonvolatile memory. In an analysis mode, a rotation amount of the motor is converted to a corresponding wavelength in accordance with the conversion table in the nonvolatile memory.

    Abstract: A spectrophotometer system including a monochrometer which scans a sample in a sample cell with discrete wavelengths of light, and measures intensity signals of at least two discrete wavelengths of light emitted from the sample. These measured intensity signals are base-line corrected by a computer with respect to reference intensity signals at corresponding wavelengths. The computer also calculates base-line corrected intensity signals for wavelengths of light intermediate said two wavelengths of light from the intensity signals of said two respective discrete wavelengths. All base-line corrected intensity signals are stored for analysis of the sample.
