Abstract:
1. An interval securing member configured to maintain a distance between an image bearing member and a developer bearing member, the image bearing member being provided rotatably and configured so that a latent image is formed thereon, the developer bearing member being configured to bear developer for developing the latent image and rotate so as to cause opposed surfaces thereof and of the image bearing member to move in the same direction, comprising: a first image bearing member side sliding contact portion configured to come into sliding contact with the image bearing member on an upstream side in a direction of rotation of the image bearing member from a nearest position where the distance between the image bearing member and the developer bearing member becomes the smallest; a first developing side sliding contact portion configured to come into sliding contact with the developer bearing member on an upstream side from the nearest position in a direction of rotation of the developer bearing member; a second image bearing member side sliding contact portion configured to come into sliding contact with the image bearing member on a downstream side from the nearest position in the direction of rotation of the image bearing member; and a second developing side sliding contact portion configured to come into sliding contact with the developer bearing member on a downstream side from the nearest position in the direction of rotation of the developer bearing member, wherein the first image bearing member side sliding contact portion and the first developing side sliding contact portion come into abutment with the image bearing member and the developer bearing member respectively, so that the interval securing member is prevented from moving in the direction of rotations of the image bearing member and the developer bearing member when the image bearing member and the developer bearing member rotate.
