Description

Technical Field

[0001] The present application relates to the technical field of copier equipment, and in particular to a split toner feeding cylinder for a copier. Background Art

[0002] A toner cartridge is a storage container used to supply developer, for example, to laser copiers. Typically, a toner cartridge for a laser copier is removably installed in the copier's developing unit. By docking the cartridge's powder outlet with the copier's powder inlet, toner from the cartridge is supplied to the photosensitive drum in the developing unit, converting the electrostatic latent image on the drum's surface into a visible image, which is ultimately fixed onto a recording medium such as paper. Currently, the toner cartridge and its main housing are integrally injection-molded. This not only requires a complex molding process but also requires complete replacement if damaged. For example, a stirring device is installed within the housing to agitate the toner in the cartridge so that the agglomerated toner can be dispersed and ejected directly from the powder outlet. However, since the toner cartridge is typically integrally injection-molded, any damage to the stirring device requires complete replacement, increasing the equipment's purchase cost.
