Abstract
PURPOSE: To obtain a picture of good quality with no white spot by bringing an elastic movable roller, opposing to a developing roller, into contact with the developing roller only in the development of an electrostatic latent image.
CONSTITUTION: Gap (l) between developing roller 12 and photoreceptor drum 1 should be 30W60μm and porous elastic roller, which is movable to the right and left as shown by arrows, moves to the right in the figure only during development to meet developing roller 12. A developer, contained in the porous member of elastic roller 11, is jetted out by being compressed in contact with developing roller 12 to contact photoreceptor drum 1, so that the edge effect type development will be carried out. Next, the development is also carried out between photoreceptor drum 1 and developing roller 12 and the proximate electrode effect is displayed effectively to stick the toner evenly to the inside of close area, so that even development can be done. At part B, squeeze roller 15 remove an excessive developer to prevent the texture from getting contaminated.
