Description

Technical Field

[0001] The utility model relates to the technical field of developing rollers, in particular to a developing roller which is easy to clean. Background Art

[0002] The toner cartridge is the core imaging device of the laser printer, and the developing roller is an important part of it. When the developing roller is working, its surface carries an electric charge (positive or negative charge depending on the brand of the machine), and absorbs toner (its function is equivalent to a magnetic roller). After the input printing data is processed, it is converted into a corresponding laser signal, which is refracted to the surface of the toner cartridge (OPC) through a set of prisms, thereby forming a latent image (a specific "image" or "text" information composed of electric charges). When the OPC rotates past the developing roller, the latent image part absorbs the corresponding toner from the surface of the developing roller to form a toner real phase. When the OPC carries the toner real phase and rotates to the corresponding position of the paper, the paper that has been treated with electrostatics will absorb the toner to the surface of the paper.

[0003] The reference authorization number is "CN217932427U", and the name is "A developer roller that is easy to clean". Although this application solves the problem that "due to dust obstruction or other equipment conditions, some carbon powder will remain on the developer roller. After a long time, it will stick to the roller surface, seriously interfering with and affecting the printing effect, and the current developer roller is not provided with a structure that can automatically clean", it still has the problem that the developer roller is difficult to remove after disassembly due to the limit of the cleaning sleeve, which affects the use of the device.
