[0154] A developing roller was produced according to the method described below.

[0155]

[0156] In a three-necked flask, Excenol 5030 (manufacturer: Asahi Glass Co., Ltd.) and TDI (manufacturer: Mitsui Chemicals, Inc.) were mixed so that the isocyanate index (number of moles of NCO / number of moles of OH) became 4.5, and a mantle heater was used It heated at liquid temperature 70 degreeC for 2 hours. The disappearance of the polyol was confirmed by the hydroxyl value method, and prepolymerized TDI was prepared.

Abstract

The purpose of the present invention is to provide a development roller with which interlayer adhesion is ensured and image defects are suppressed. In order to achieve the foregoing, this developmentroller comprises, at least a shaft, an elastic layer formed on the shaft, and a coating layer formed on the elastic layer, wherein the development roller is characterized in that: an adhesive layer isprovided between the elastic layer and the coating layer at both ends of the elastic layer in the axial direction of the development roller; the adhesive layer adheres to the elastic layer and the coating layer; and the adhesive layer is obtained by curing an adhesive layer-use composition containing a moisture-curing adhesive agent and a thixotropic additive agent.

Description

technical field [0001] The present invention relates to a developing roller and a manufacturing method of the developing roller. Background technique [0002] In the developing roller, seal members are sometimes provided at both axial ends of the developing roller in order to prevent toner from leaking out. In this type of developing roller, when the developing roller rotates, sometimes the end of the developing roller is worn or the layer forming the developing roller is peeled off. [0003] Patent Document 1 discloses a technique of providing an adhesive layer for improving adhesion between layers on at least one end portion in the axial direction of a developing roller, thereby preventing peeling of layers in the end portion of the developing roller, In turn, the wear of the end portion of the developing roller is reduced. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2008-040241 Contents of the inv...
