Document Type and Number:
WIPO Patent Application WO/2001/068372
Kind Code:
A1
Abstract:
An optical write head capable of correcting a sub-scanning-direction deviations, caused by variations in rod lens production quality, of light spot rows on a photosensitive drum, comprising a self-scanning light emitting device array and a rod lens array for projecting light beams from the light emitting device array onto the photosensitive drum, wherein a generating timing of a start pulse supplied for each chip to a start pulse line is regulated to correct deviations of light spot rows.
