Patent JP-H1024619-A (JP)
Title: Image forming device
Inventor: GOTO TATSUYA
IPC: B41J2/455
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To inhibit image defects such as magnification variation, color shift and density variation by providing recording heads, each of which is equipped with light emitting elements, and selectively causing the light emitting elements to emit light in accordance with image information and at the same time, enabling the emission of the light emitting elements even at any time other than when an image is formed. SOLUTION: An LED array 213 for black is lighted and heated up properly, getting close to a temperature T, during the period of which image information is not sent to LED arrays for yellow, magenta and cyan 210, 211, 212 light emitting elements for image exposure are lighted. When an image in black alone is formed, it is controlled so that every light emitting element is lighted in such a state that an image formation process such as development and transfer is not performed in yellow, magenta and cyan image forming parts 317, 318, 319. Consequently, if a full-color image is created immediately after the formation of an image in black, each of LED arrays is uniformly heated up, so that color shift and density irregularities can be prevented from being generated.
