Title: Image forming device
Inventor: NAKAJIMA TETSUO
IPC: G03G15/00
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent the edge effect of leading edge and trailing edge in printing a solid pattern and to make the density thin to a appropriate density by adjusting exposure by an exposure means by the number of scanning lines equivalent to a specified width of the leading edge and the trailing edge. SOLUTION: The opposed surfaces of a photoreceptor drum 1a and a developing roller 40a (to 40d) are rotated in the same direction, and rotated in a state where the circumferential speed V1 of the drum 1a is equal to the circumferential speed V2 of the roller 40a (to 40d). By impressing voltage Vb between the drum 1a and a developing device, the surface of the drum 1a is electrified (potential Vs), and the drum 1 is irradiated with a laser beam based on the impressed data by a laser exposure device 3a, so that an electrostatic latent image is formed. In the case where the printing data is the solid pattern, the exposure for the leading edge and the trailing edge in printing the solid pattern is adjusted.  In such a case, the irradiating pulses of the laser beam are thinned in a leading edge area and a trailing edge area, thereby, irradiation time is shortened and the quantity of laser beam is reduced.
