An image forming apparatus (1) includes an image carrier unit (15) and a positioning member (30) configured to position the image carrier unit (15) to the apparatus main body (2). The image carrier unit (15) has a concentric circumference part (51L), (51R) formed on a concentric circle with a rotating shaft (9a) of the image carrier (9) and the apparatus main body (2) has an edge part (42L), (42R) facing the concentric circumference part (51L), (51R) at the attachment position. The positioning member (30) has an intervening part (37) formed with an edge side abutment face (37a) facing the edge part (42L), (42R) of the apparatus main body (2) and a unit side abutment face (37b) facing the concentric circumference part (51L), (51R) of the image carrier unit (15). |
