Title:
Develop equipment, process cartridges, and image forming equipment
Document Type and Number:
Japanese Patent JP6308836
Kind Code:
B2
Abstract:
A developing device includes a developer carrying member that carries developer; a frame member that supports the developer carrying member; a sealing section that faces a peripheral surface of the developer carrying member and suppresses leakage of the developer; and an interval ensuring member that maintains a distance between the image carrying member and the developer carrying member. The interval ensuring member includes a movement regulating portion that prevents movement of the interval ensuring member in a rotation direction of the developer carrying member when the image carrying member and the developer carrying member rotate, and a maintaining portion that contacts the image carrying member and the developer carrying member for maintaining the distance between the image carrying member and the developer carrying member. The maintaining portion and the sealing section are positioned in a predetermined cross section that is orthogonal to an axial line of the developer carrying member.
