A fuser fixes a toner image on a paper sheet. A first sheet detecting sensor is arranged in an upstream side of the fuser in a sheet transportation path, and detects passing timings of front and rear ends of the paper sheet. A second sheet detecting sensor is arranged in a downstream side of the fuser in a sheet transportation path, and detects passing timings of front and rear ends of the paper sheet. An anomaly detecting unit detects anomaly of the humidity sensor on the basis of (a) a ratio or difference between a first sheet length based on the passing timings detected by the first sheet detecting sensor and a second sheet length based on the passing timings detected by the second sheet detecting sensor and (b) a measurement value of the humidity sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus having abnormality detection unit for humidity sensor","description":"In an image forming apparatus, a humidity sensor measures a humidity.
