Abstract

PURPOSE: To easily obtain two images on one body to be irradiated by light by so constituting 1st and 2nd image optical paths in that light may be irradiated approximately onto the same point, shutting off the 1st image optical path and forming the images in the shut region by means of the 2nd image optical path.
CONSTITUTION: When a polarizing plate 29 is drawn out from a spool 30 to the position M and further when a polarizing plate 36 is drawn out up to the position of N from a spool 38 positioned on the side opposite from the spool 30, the 1st image optical path L1 is shut of between the M and N where the polarizing plates 29, 36 are superposed. In the invidual polarizing plate parts other than these, the 1st optical path L1 is not shut off and allows the transmission of light, thus the image is projected to the circumferential suface of the photosensitive drum. In this way, the images are formed by the 2nd image optical path L2 to the image forming region where the 1st image forming optical path L1 is shut off. In this way, the two images may be easily formed on one body to be irradiated with light with the simple constitution.
