Thereafter, the CPU performs image formation control such that a phase adjustment image is formed on a recording medium, and determines a phase adjustment value based on an adjustment value input by the user. The CPU sets the phase adjustment value in the optical scanning apparatus to correct the phase shift. Thus, when the first correction is to be executed, the CPU executes the second correction before executing the first correction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus","description":"In an image forming apparatus including multiple light emitting elements, upon receiving an instruction from a user to execute correction (first correction) of a phase shift due to a shift in the rela","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9645521","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.
