Abstract
An image forming apparatus includes a latent image bearer, a charger, a blower, a first detector, and a second detector. The charger charges a surface of the latent image bearer. The blower sends air to around the charger. The first detector detects a temperature of the air to be sent to around the charger. The second detector detects a temperature around the charger. The blower performs an operation based on a detection result of the first detector and a detection result of the second detector.
Claims17
An image forming apparatus comprising:
- a latent image bearer;
- a charger to charge a surface of the latent image bearer;
- a blower to send air to around the charger;
- a first detector to detect a temperature of the air to be sent to around the charger;
- and
- a second detector to detect a temperature around the charger,
- wherein the blower is configured to perform an operation based on at least one of a detection result of the first detector and a detection result of the second detector, and wherein, when the detection result of the first detector is relatively higher than a set temperature, the blower is configured to be continuously driven until an end of an image forming operation, regardless of the detection result of the second detector.
