    摘要: 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.

    摘要: An image forming apparatus includes a plurality of image carriers, an intermediate transfer body, a plurality of primary transfer members, a secondary transfer member, a first guide member, and a controller. The first guide member guides a recording medium along a conveying direction. The controller controls a primary transfer bias and a secondary transfer bias. A plurality of the primary transfer members include an upstream side primary transfer member and a downstream side primary transfer member. The controller makes an absolute value of the primary transfer bias applied to the downstream side primary transfer member larger than an absolute value of the primary transfer bias applied to the upstream side primary transfer member. The controller lowers an absolute value of the secondary transfer bias when the recording medium separates from the first guide member.

Upon application of the superimposed transfer bias to the transfer device, the sheet separation bias applied to the sheet separation device is changed from the sheet separation bias applied upon application of the DC transfer bias to the transfer device.
