Title: Image forming device
Inventor: KAWASE MICHIO
IPC: B41J2/525
Filed: 1990-10-12
Abstract: PURPOSE:To stably read an image pattern for correcting registration by making energy for forming a pattern substantially larger in the case of forming a pattern for aligning registration than in the case of forming an image in accordance with an image signal which should be reproduced. CONSTITUTION:The energy for forming the pattern is made substantially larger in the case of forming the pattern for aligning the registration than in the case of forming the image in accordance with the image signal which should be reproduced. Namely, in the case of forming the image pattern for correcting the registration, a PWM image signal at the time of ordinarily forming the color image is not used but the image pattern signal for correcting the registration is used so as to control the on/off of a laser beam. In such a case, the image pattern is formed by continuously and fully turning on a laser by as much as two picture elements according to the data of the image pattern, so that a read peak is not separated and becomes one. Thus, the accuracy of the reading position of the image pattern for correcting the registration is improved and a read error is prevented.
