To prevent a pressing force from a transfer member to an image holding body from being reduced by a tensile force applied to a continuous medium.SOLUTION: An image forming apparatus (U) comprises: a transfer member (T2b) that sandwiches a continuous medium (S) with an image holding body (B) and is pressed against the image holding body (B), and transfers an image on the surface of the image holding body (B) to the continuous medium (S); a first guide member (1) that is arranged on the upstream side adjacent to the transfer member (T2b) with respect to the conveyance direction of the medium (S) and guides the medium (S); and a second guide member (2) that is arranged on the downstream side adjacent to the transfer member (T2b) with respect to the conveyance direction of the medium (S) and guides the medium (S), wherein an outer surface of the transfer member (T2b) is set on a side farther from the image holding body (B) with respect to a virtual line that is a common tangent (3) of the first guide member (1) and second guide member (2).SELECTED DRAWING: Figure 3 【課題】連続媒体に付与される張力により転写部材から像保持体への押圧力が弱まることを抑制すること。【解決手段】像保持体（Ｂ）との間で連続する媒体（Ｓ）を挟み且つ像保持体（Ｂ）に押しつけられ、像保持体（Ｂ）の表面の画像を連続する媒体（Ｓ）に転写する転写部材（Ｔ２ｂ）と、媒体（Ｓ）の搬送方向に対して、転写部材（Ｔ２ｂ）の上流側に隣り合って配置され、媒体（Ｓ）を案内する第１の案内部材（１）と、媒体（Ｓ）の搬送方向に対して転写部材（Ｔ２ｂ）の下流側に隣り合って配置され媒体（Ｓ）を案内する第２の案内部材（２）と、を備え、第１の案内部材（１）と第２の案内部材（２）との共通接線（３）である仮想線に対して、像保持体（Ｂ）から遠い側に、転写部材（Ｔ２ｂ）の外表面が設定された画像形成装置（Ｕ）。【選択図】図３
