【課題を解決するための手段】
請求項１に記載の発明は、トナー像を担持する像担持体に対して接離可能に設けられ、前記像担持体に接したとき、この像担持体上の残留トナーを除去するクリーニング部材と、前記クリーニング部材を前記像担持体に接離させる接離手段と、前記クリーニング部材の位置を検知する検知手段とを備えるクリーニング装置であって、前記検知手段は、発光素子と、受光素子と、前記接離手段の動作に連動して前記発光素子と受光素子との間の光路を遮蔽する遮蔽部材と、前記発光素子の発光面と前記受光素子の受光面とに接触して清掃する清掃部材とを備えることを特徴とする。 0007
[Means for solving problems]
The invention according to claim 1 is a cleaning member that is provided so as to be detachable from an image carrier that supports a toner image and that removes residual toner on the image carrier when it comes into contact with the image carrier. and moving means for contacting and separating the cleaning member to the image charge of lifting body, wherein a cleaning device and a detection means for detecting the position of the cleaning member, wherein the sensing means includes a light emitting element, a light receiving element and a shielding member for shielding an optical path, in contact with the light receiving surface of the light emitting surface and the light receiving element before Symbol emitting element cleaning between the light emitting element in conjunction with the operation of the moving means and the light receiving element It is characterized by being provided with a cleaning member.

しかし、清掃部材が、接離手段の動作に連動して、発光素子及び受光素子の表面を清掃する。清掃部材が、発光素子及び受光素子の表面を清掃することにより、発光素子及び受光素子の表面に残留トナー等が付着しにくくなるので、検知手段の機能の低下を防止できる。 However, Kiyoshi Kamon material, in conjunction with the operation of the moving means, for cleaning the surface of the light emitting element and the light receiving element. By cleaning the surfaces of the light emitting element and the light receiving element with the cleaning member, residual toner and the like are less likely to adhere to the surfaces of the light emitting element and the light receiving element, so that deterioration of the function of the detecting means can be prevented.

Claims

Separable therefrom provided with respect to the image carrier for carrying a toner image, when in contact with the image bearing member, a cleaning member for removing residual toner on the image bearing member, said image responsible lifting the cleaning member A cleaning device comprising contact / separation means for contacting / separating with a body and detection means for detecting the position of the cleaning member,
The detection means, the light emitting element, a light receiving element, the light emitting device in conjunction with the operation of said moving means and a shielding member for shielding an optical path between the light receiving element, a light emitting surface before Symbol emitting element cleaning apparatus, characterized in that it comprises a cleaning member for cleaning in contact with the light receiving surface of the light receiving element.

2. The cleaning according to claim 1, wherein the contacting / separating means includes a cam that rotates about an axis, and the cleaning member contacts and separates from the image carrier according to a cam surface by the rotation of the cam. apparatus.

When the cleaning member is in a shorter state of the time of contact with the image carrier and the time of separation, the shielding member is positioned between the light emitting element and the light receiving element. The cleaning device according to claim 1, wherein the cleaning device is provided.

The cleaning device according to claim 1, wherein the cleaning member is a brush.
