Document Type and Number:
Japanese Patent JP3607790
Kind Code:
B2
Abstract:
The invention avoids an increase in the number of parts and components which form an apparatus for forming an image, and hence, prevents a main body of the image forming apparatus from completed in a large size. To this end, the image forming apparatus comprises yellow, magenta, cyan and black photosensitive drums 7Y, 7M, 7C and 7B, chargers 8Y, 8M, 8C and 8B which respectively charges the photosensitive drums 7Y, 7M, 7C and 7B which correspond to the respective colors, laser diodes 11Y, 11M, 11C and 11B which generate laser beams representing the respective colors in accordance with image signals, the laser beams exposing the respective photosensitive drums 7Y, 7M, 7C and 7B so that electrostatic latent images are formed on the photosensitive drums 7Y, 7M, 7C and 7B which correspond to the respective colors, developing members 31Y, 31M, 31C and 31B corresponding to the respective colors for supplying developing agents, a polygon mirror 13 for scanning the laser beams representing the respective colors emitted from the laser diodes 11Y, 11M, 11C and 11B, and a reflection mirror 15 for reflecting the laser beams which are indicative of the respective colors in such a manner that the laser beams intersect with each other at the same intersection B and thereafter respectively irradiate the photosensitive drums 7Y, 7M, 7C and 7B which correspond to the respective colors.
