摘要： PROBLEM TO BE SOLVED: To provide a developing device that enables easy attachment of a developing agent leakage prevention member while preventing occurrence of wrinkles in a layer of the developing agent leakage prevention member coming into contact with an outer circumferential surface of a developing agent carrier, to thus prevent leakage of a developing agent from the outer circumferential surface of the developing agent carrier. SOLUTION: In a side seal 61, an adhesive layer 70 partially bonds an opposing surface (first opposing surface 63A) of a first layer 63 that is configured to come into contact with an outer circumferential surface of a developing roller 26 opposing to a second layer 64 that comes into contact with a lower mount 52 to an opposing surface (second opposing surface 64A) of the second layer 64 opposing the first layer 63 such that an unbonded area X where the opposing surfaces are not bonded together is produced. Therefore, the first layers 63 are less susceptible to influence of deformation of the second layers 64 as compared with the case where the entireties of the first opposing surfaces 63A are bonded to the second opposing surfaces 64A, hence, occurrence of the wrinkles in the first layers 63, which is caused along with deformation of the second layers 64, is prevented. It is easy to bond the first layers 63 to the second layers 64. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种显影装置，其能够容易地附着显影剂泄漏防止部件，同时防止显影剂泄漏防止部件的层中的褶皱与显影剂泄漏防止部件的外周面接触从而防止显影剂从显影剂载体的外周表面泄漏。解决方案：在侧密封件61中，粘合剂层70部分地粘合第一层63的相对表面（第一相对表面63A），该第一层63被构造成与显影辊26的外周面相接触与第二层64相对的第二层64与第二层64相对的第二层64接触到与第一层63相对的相对表面（第二相对表面64A），从而产生相对表面未结合在一起的未结合区域X. 因此，与第一相对面63A的整体结合到第二相对面64A的情况相比，第一层63不易受到第二层64的变形的影响，因此在第一层63中发生褶皱防止了与第二层64的变形一起引起的层63。将第一层63粘合到第二层64是容易的。版权所有（C）2009，JPO和INPIT

摘要： PROBLEM TO BE SOLVED: To provide a developing device capable of securing the excellent exposure of an image carrier in constitution where a supporting member and a leaf spring member are fixed by adhesion, and an image forming apparatus equipped therewith. SOLUTION: The supporting member 53, and the leaf spring member 54 extended from the supporting member 53 toward a developing roller are stuck and fixed by an adhesive layer comprising a double-coated adhesive tape 109. In this constitution, the double-coated adhesive tape 109 is stuck to a position separate by predetermined width from the base edge to the tip end side of the leaf spring member 54 on the opposed surface of the leaf spring member 54 to the supporting member 53. Thus, a portion of the predetermined width from the base edge of the leaf spring member 54 is opposed to the supporting member 53 without interposing the double-coated adhesive tape 109, whereby the double-coated adhesive tape 109 does not project from space between the base edge of the leaf spring member 54 and the supporting member 53.
