Abstract:
Provided is an inexpensive image forming apparatus capable of monitoring the generating state of various powders. The image forming apparatus includes a minute-particle-measuring device, a toner-particles-detecting air duct, a paper dust-detecting air duct, and blower fans. The minute-particle-measuring device detects the concentration of minute particles in air. The toner-particle-detecting air duct is an air duct leading from the image forming unit to the minute-particle-measuring device. The paper-dust-detecting air duct is an air duct leading from the paper-conveying path to the minute-particle-measuring device. The blower fans are respectively provided in the toner-particle-detecting air duct and the paper-dust-detecting air duct, and generate airflow that flows toward the minute-particle-measuring device side. The blower fans in the toner-particle-detecting air duct and in the paper-dust-detecting air duct are switched.

Claim (Index 3):
An image forming apparatus comprising plural image forming units for forming respective image patterns using plural types of toner that are configured with toner powder that differs from each other, and a paper-conveying path for conveying paper to locations where the image patterns are transferred to the paper; and further comprising:\n a minute-particle-measuring device for detecting the concentration of minute particles in air; plural toner-particle-detecting air ducts as air ducts leading from the respective plural image forming units to the minute-particle-measuring device; and blower fans that are respectively provided in the plural toner-particle-detecting air ducts, and that generate air flow that flows toward the minute-particle-measuring device side; wherein the blower fans in the respective plural toner-particle-detecting air ducts are set to operate by being switched.
