Abstract
An image-forming apparatus include an image bearer; a cleaning device to clean a surface of the image bearer; an air-blowing device to blow outside air; a temperature/humidity detector to detect temperature and humidity outside of the image-forming apparatus; and a controller to determine absolute humidity from detected temperature and humidity. Based on the absolute humidity, a waiting time from a time when a previous image-forming operation ends until the air-blowing device stops, in a stand-by state of an image-forming operation, and an unused time from a time when the air-blowing device stops until the air-blowing device resumes, the controller determines whether or not a polishing operation of the image bearer by the cleaning device after the air-blowing device is unused is executed in starting the operation of the blowing device.
