An image forming apparatus includes an apparatus body, a sheet supporting portion, a sheet feeding portion configured to feed a sheet supported on the sheet supporting portion, a sheet regulation portion configured to regulate a position of the sheet in a width direction, an image forming portion including an exposing portion configured to expose a charged surface of an image bearing member, the image forming portion being configured to form an image on the sheet fed by the sheet feeding portion, and a frame member provided inside the apparatus body. A position of the exposing portion is determined with respect to the frame member. A position of the sheet regulation portion is determined with respect to the frame member.
Claims13
An image forming apparatus comprising:
- a sheet supporting portion configured to support a sheet thereon;
- a sheet feeding portion configured to feed the sheet supported on the sheet supporting portion;
- a sheet regulation portion configured to regulate a position of the sheet supported on the sheet supporting portion in a width direction perpendicular to a feeding direction in which the sheet is fed;
- an image forming portion comprising an image bearing member configured to rotate, a charging portion configured to charge a surface of the image bearing member, an exposing portion configured to expose the charged surface of the image bearing member to form an electrostatic latent image, and a developing portion configured to develop the electrostatic latent image formed on the image bearing member with toner, the image forming portion being configured to form an image on the sheet fed by the sheet feeding portion;
- an apparatus body including
- a first side frame located on an outside of a first end of the image forming portion in the width direction, and
- a second side frame located on an outside of a second end of the image forming portion in the width direction;
- and
- a frame member connected to the first side frame and the second side frame,
- wherein the frame member includes an exposing portion positioning portion configured to determine the position of the exposing portion with respect to the frame member and a sheet regulation portion positioning portion configured to determine the position of the sheet regulation portion with respect to the frame member.
