Description
本発明は、第1の方向に沿って複数の発光部が配列されている光源を含み、画像情報に応じて前記第1の方向に直交する第2の方向に光束を射出する光学ヘッドと;前記光学ヘッドからの光束の光路上に配置され、前記第1の方向を長手方向とし、該第1の方向に平行な軸回りに回転可能であり、その表面に潜像が形成される像坦持体と;前記光学ヘッドと前記像坦持体との間に、前記第1の方向に関してそれぞれ異なる位置に配置され、前記光学ヘッドと前記像坦持体との距離を規定する複数の規定機構と;を備え、前記複数の規定機構のうちの少なくとも1つの規定機構は、前記光学ヘッドと前記像坦持体との距離を変更するための調整機構と、前記第1の方向及び前記第2の方向のいずれにも直交する第3の方向に離間している2つの突き当て部材とを有し、該2つの突き当て部材は、いずれも前記像坦持体、及び前記像坦持体に付随している部材のいずれかと接触している画像形成装置である。 The present invention includes an optical head that includes a light source in which a plurality of light emitting units are arranged along a first direction, and emits a light beam in a second direction orthogonal to the first direction according to image information; An image carrier that is disposed on the optical path of the light beam from the optical head, can rotate about an axis parallel to the first direction, and has a latent image formed on the surface thereof. A plurality of defining mechanisms which are arranged at different positions with respect to the first direction between the optical head and the image carrier and define the distance between the optical head and the image carrier. And at least one of the plurality of defining mechanisms includes an adjustment mechanism for changing a distance between the optical head and the image carrier, the first direction, and the second Two spaced apart in a third direction orthogonal to any of the directions And a come contact member, the two abutment members are both the image-bearing member, and images forming device that has been in contact with any of the members that are associated with the image-bearing member.
