A method of manufacturing a frame unit from a first unit, in which the first unit comprises, a first image carrying member that is configured to carry an electrostatic latent image, wherein the first image carrying member includes a first edge portion member and the first edge portion member includes a first restricted portion, a supporting member that supports the first image carrying member, wherein the supporting member includes a bearing that is configured to engage with the first edge portion member so that the first image carrying member is rotatable about a rotational axis, and a frame to which the supporting member is fixed, the frame including a first end portion to which the supporting member is fixed, a second end portion opposite to the first end portion in a direction of the rotational axis, a first restricting portion that is configured to restrict movement of the first image carrying member, wherein in a direction orthogonal to the rotational axis, the first restricting portion protrudes towards the first image carrying member, and the first restricting portion is configured to abut against the first restricted portion if the first restricted portion is moved towards the second end portion from the first end portion in the direction of the rotational axis, wherein with respect to the direction of the rotational axis, a position of the first restricting portion and a position of the bearing overlap each other at least partially, and wherein when viewed in the direction of the rotational axis, the first restricting portion is arranged to overlap a first circle (63R1) drawn by the first restricted portion if the first image carrying member is rotated about the rotational axis, the method of manufacturing the frame unit from the first unit comprising: a separating step in which the first image carrying member is separated from the supporting member, characterized in that the supporting member is adhered to the frame, and the first image carrying member is separated from the supporting member while the supporting member is adhered to the frame in the separating step, and the supporting member is elastically deformable in a state in which the first edge portion member and the bearing abut against each other. the first unit comprises, a first image carrying member that is configured to carry an electrostatic latent image, wherein the first image carrying member includes a first edge portion member and the first edge portion member includes a first restricted portion, a supporting member that supports the first image carrying member, wherein the supporting member includes a bearing that is configured to engage with the first edge portion member so that the first image carrying member is rotatable about a rotational axis, and a frame to which the supporting member is fixed, the frame including a first end portion to which the supporting member is fixed, a second end portion opposite to the first end portion in a direction of the rotational axis, a first restricting portion that is configured to restrict movement of the first image carrying member, wherein in a direction orthogonal to the rotational axis, the first restricting portion protrudes towards the first image carrying member, and the first restricting portion is configured to abut against the first restricted portion if the first restricted portion is moved towards the second end portion from the first end portion in the direction of the rotational axis, wherein with respect to the direction of the rotational axis, a position of the first restricting portion and a position of the bearing overlap each other at least partially, and wherein when viewed in the direction of the rotational axis, the first restricting portion is arranged to overlap a first circle (63R1) drawn by the first restricted portion if the first image carrying member is rotated about the rotational axis, the method of manufacturing the frame unit from the first unit comprising: a separating step in which the first image carrying member is separated from the supporting member, characterized in that the supporting member is adhered to the frame, and the first image carrying member is separated from the supporting member while the supporting member is adhered to the frame in the separating step, and the supporting member is elastically deformable in a state in which the first edge portion member and the bearing abut against each other. a separating step in which the first image carrying member is separated from the supporting member, characterized in that the supporting member is adhered to the frame, and the first image carrying member is separated from the supporting member while the supporting member is adhered to the frame in the separating step, and the supporting member is elastically deformable in a state in which the first edge portion member and the bearing abut against each other.
