Zusammenfassung:To provide means that continues transferring developer images to labels without interrupting print processing even in an image forming apparatus employing a secondary transfer system.SOLUTION: An image forming apparatus comprises: a roll sheet in which a plurality of labels are attached to a belt-like mount at a predetermined gap in a peelable manner; an image forming unit that forms developer images on the basis of print data; an intermediate transfer body to which the developer images formed by the image forming unit are transferred; a transfer unit that transfers the developer images transferred to the intermediate transfer body to the labels; a defect detection sensor that detects defects of the labels. When the defects of the labels are detected by the defect detection sensor, the image forming apparatus executes transfer prevention procedures to prevent transfer of the developer images performed by the transfer unit when defective parts pass through the transfer unit.SELECTED DRAWING: Figure 5 【課題】2次転写方式の画像形成装置であっても、印刷処理を中断することなくラベルへの現像剤像の転写を継続する手段を提供する。【解決手段】画像形成装置が、帯状の台紙に、所定の隙間を介して複数のラベルを剥離可能に貼付したロール紙と、印刷データを基に、現像剤像を形成する画像形成部と、前記画像形成部で形成した現像剤像を転写する中間転写体と、前記中間転写体に転写された現像剤像を前記ラベルに転写する転写部と、前記ラベルの欠損を検出する欠損検出センサと、を備え、前記欠損検出センサにより前記ラベルの欠損を検出した場合は、当該欠損部が前記転写部を通過するときに、前記転写部による前記現像剤像の転写を防止する転写防止処置を実行する。【選択図】 図5
