Image forming apparatus performing a corona products removal mode |
摘要 |
An image forming apparatus includes an image bearer; a charger to charge a surface of the image bear; a developing device to develop a toner image on the surface of the image bearer; an image bearer cleaner to remove residual toner remaining on the surface of the image bearer after a transfer process; and a controller to cause the image forming apparatus to perform, before a start of printing operation, a corona products removal mode. In the image forming apparatus further including a temperature and humidity sensor to measure temperature and humidity of an ambient environment of the image bearer, the controller to cause the image forming apparatus to perform, before a start of an image forming operation, a corona products removal mode based on an absolute humidity obtained by the temperature and humidity detected by the temperature and humidity sensor. |
