AI Technical Summary
Technical Problem
Existing image-forming apparatuses with scanning lenses lacking F-θ characteristics face challenges in maintaining uniform pixel exposure due to non-uniform scanning speeds, leading to image degradation.
Method used
An image-forming apparatus with a controller that adjusts scanning periods for pixels at central and non-central regions, ensuring equal light-emitting time lengths while allowing non-constant linear scanning speeds, thereby maintaining consistent exposure across the image area.
Benefits of technology
This solution ensures consistent toner densities across different regions of the image, improving image quality by maintaining exposure amounts uniform, even without F-θ lens correction.
