Image forming apparatus

An image forming apparatus comprising:

• a plurality of rotating members that are rotatable;
• an annular circulating member that is wound around the plurality of rotating members and circulates when the rotating members rotate;
• a retaining member attached to an attaching portion of the circulating member and that circulates together with the circulating member, the retaining member being configured to retain a recording medium in an area where the attaching portion comes into contact with one of the rotating members;
• an image forming section that forms an image on the recording medium at an image forming position defined on a circulation path along which the circulating member circulates;
• a delivering unit that delivers the recording medium to a retaining position where the recording medium is to be retained by the retaining member;
• a detector that detects rotation of the one rotating member;
• and
• a controller that controls delivery of the recording medium from the delivering unit to the retaining position, the delivery being controlled with reference to information detected by the detector,
• wherein the one rotation member is positioned upstream of the image forming position on the circulation path.
