An image forming apparatus (1) includes a plurality of image carriers (7Y, 7C, 7M, 7K), an intermediate transfer body (11), a plurality of primary transfer members (12Y, 12C, 12M, 12K), a secondary transfer member (21), a first guide member (31), and a controller (40). The first guide member (31) guides a recording medium (S) along a conveying direction. The controller (40) controls a primary transfer bias and a secondary transfer bias. A plurality of the primary transfer members (12Y, 12C, 12M, 12K) include an upstream side primary transfer member (12Y, 12C, 12M) and a downstream side primary transfer member (12K). The controller (40) makes an absolute value of the primary transfer bias applied to the downstream side primary transfer member (12K) larger than an absolute value of the primary transfer bias applied to the upstream side primary transfer member (12Y, 12C, 12M). The controller (40) lowers an absolute value of the secondary transfer bias when the recording medium (S) separates from the first guide member (31). |
