An image forming apparatus includes: an intermediate transfer member onto which a image is primarily transferred from an image forming unit; a transfer unit to secondarily transfer the image from the intermediate transfer member to a media at a secondary-transfer position; a conveying unit configured to convey the media to the secondary-transfer position; and a conveying speed controller to control a speed of conveying the media. The conveying unit includes a first detector and a second detector downstream the first detector and upstream the secondary-transfer position. Based on a detection of the media by the first detector and a timing at which the image forming unit forms the image, the conveying speed controller changes the conveying speed until the second detector detects the media and changes, after the second detector detects the media, the conveying speed to a speed substantially the same as the intermediate transfer member speed.
