Image forming system and non-transitory computer readable medium

Abstract

PROBLEM TO BE SOLVED: To provide an image forming apparatus that can effectively reduce the occurrence of image failure and generation of a discharge product by correcting a charge voltage according to a change in electrical characteristic of a photosensitive layer on a surface of an image carrier. SOLUTION: An image forming apparatus comprises: an image carrier on a surface of which a photosensitive layer is formed; a charging device that charges the surface of the image carrier; a voltage application device; a temperature and humidity detection device; a time measuring unit; and a control unit. The voltage application device applies a charge voltage to the charging device. The temperature and humidity detection device detects the temperature and humidity around the image carrier. The time measuring unit measures a low-humidity environment standing time during which the image carrier is continuously in a non-driving state while the humidity detected by the temperature and humidity detection device is equal to or less than a predetermined value, and when the humidity detected by the temperature and humidity detection device exceeds the predetermined value, resets the low temperature environment standing time. The control unit sets the amount of correction of the charge voltage on the basis of the temperature and humidity detected by the temperature and humidity detection device, and changes the amount of correction of the charging voltage on the basis of the low-humidity environment standing time.
