<p>PURPOSE:To prevent the rear edge of copying paper from curving upward and to eliminate a transfer shift, by arranging an upper and a lower paper guide plate between a photosensitive drum and a couple of resist rolls, and curving the copying-paper passage surface side of the upper guide plate. CONSTITUTION:One end part 13' of the upper paper guide plate 13 is arranged so that an angle theta formed between the straight line G connecting the centers of rotation of the upper and lower resist rolls 16 and 17 and the line connecting the center of rotation of the upper roll 16 and one end part 13' of the upper guide plate 13 is <90 deg., i.e. acute angle; and the copying paper passage surface side of the upper paper guide plate 13 is made into a curved surface. Therefore, the rear edge part of the copying paper 3 fed out by the resist rolls 16 and 17 moves along the circumferential surface of the upper roll 16 without curving upward and contacts one end part 13' of the upper paper guide plate 13, and it ia fed in along the curved surface of the upper paper guide plate 13 to transfer an image excellently.</p> |
