The controller is configured to control the image forming unit to form a test chart on a sheet, to control the reader image processor to detect the dust on the transparent member based on a result of reading the test chart, and to generate a conversion condition based on other signal values excluding an abnormal signal value caused by the dust on the transparent member."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus","description":"An image forming apparatus includes an image forming unit configured to form an image, a reader having a transparent member, the reader being configured to read an original through intermediation of t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11265424","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.
