An image forming apparatus includes a driving unit configured to apply a driving force to a photosensitive drum, in which the driving unit includes a first driving frame hold a shaft joint side of a driving gear, a second driving frame hold a side opposite to the shaft joint side of the driving gear and be located coaxially with the first through-hole, a first driving frame wall portion extend in an axial direction of the driving gear toward the second driving frame, and a second driving frame wall portion extend in the axial direction toward the first driving frame, and an elastic member is compressed and held in a gap between the first driving frame wall portion and the second driving frame wall portion.

Image forming apparatus

An image forming apparatus includes: a motor which is provided in a housing of the image forming apparatus; a first gear which includes a rotation shaft axially supported by the housing; a first bearing and a second bearing which support the rotation shaft of the first gear and are arranged on one side and the other side of the first gear; a second gear which includes a rotation shaft and meshes with the first gear; a rotating member to which the second gear is attached and which is rotatable with respect to the housing so as to be positioned at a first position at which the first gear and the second gear mesh with each other and at a second position at which the second gear is separated from the first gear; a third bearing and a fourth bearing which support the rotation shaft of the second gear and are arranged on one side and the other side of the second gear; and a holding member which is provided in the housing integrally holds the first bearing and the second bearing, the holding member having a first groove portion which is formed on a movement locus of the third bearing moving by the rotation of the rotating member, into which the third bearing enters when the rotating member moves from the second position to the first position, and which holds the third bearing when the rotating member is positioned at the first position, and the holding member having a second groove portion which is formed on a movement locus of the fourth bearing moving by the rotation of the rotating member, into which the fourth bearing enters when the rotating member moves from the second position to the first position, and which holds the fourth bearing when the rotating member is positioned at the first position.
