The determination unit determines a drive current for performing switch-driving of the plurality of light-emitting portions, based on image data, the drive current corresponding to the first drive current and the bias current upon the image data being generated in a second section of a non-image period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus that forms image using a plurality of light beams","description":"A determination unit determines a bias current caused to flow through at least plurality of light-emitting portions regardless of image data during an image period by determining a first drive current","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9658559","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
