Abstract
An image forming apparatus includes a photosensitive drum and an apparatus main body, the apparatus main body includes a transfer roller exerting a transfer pressing force on the photosensitive drum, a positioning portion positioning the photosensitive drum in first and second directions by being contacted by a bearing portion holding a rotation axis of the photosensitive drum, the first direction being in a virtual plane perpendicular to the rotation axis, and the second direction being a direction intersecting the first direction, and a pressing member exerting a holding-and-pressing force pressing the bearing portion toward the positioning portion, and, in a state in which the bearing portion is in contact with the positioning portion, the holding-and-pressing force has a component force in the first direction, and the transfer pressing force has a component force in the second direction that is oriented to press the bearing portion toward the positioning portion.
