Abstract: PURPOSE:To obtain a contour image as a positive image by forming a positive electrostatic latent image where the contour part of an original image part is left as a high potential part on the surface of an electrostatic latent image carrier in the 2nd electrostatic charging process and further performing normal development in a developing process. CONSTITUTION:In the 2nd electrostatic charging process, the surface of a photosensitive drum 1 where an electrostatic latent image is formed is given a charge having the opposite polarity from the electrostatic latent image by a scorotron charger 4, and a voltage of +200V is applied to a grid 42.

Furthermore, the inflection form is modified into a 5-stage inflection and the inflection pattern is set to the inflection form. Moreover, a node of an auxiliary verb 'masu(polite form of 'is')' and a node of an auxiliary verb (n) are added. When the input sentence is a 3rd inflection type, a node of an auxiliary verb 'desu(polite form of 'is')' is added.
