Abstract
An image forming apparatus includes an image carrying member, a charging device, an exposure device, a development device, a development voltage power supply, a humidity detection device and a controller. The exposure device exposes the surface of the image carrying member charged by the charging device to form an electrostatic latent image. The development device includes a development container which stores a developer including a toner and a developer carrying member which supplies, to the image carrying member, the toner in the developer, and develops the electrostatic latent image into a toner image. The development voltage power supply applies, to the developer carrying member, a development voltage with an alternating voltage superimposed on a direct voltage. The humidity detection device detects an absolute humidity around the development device. The controller stepwise increases the frequency of the alternating voltage as the absolute humidity detected by the humidity detection device is increased.
