Gap controlling structure for image forming apparatus

摘要

A gap controlling structure for image forming apparatus for maintaining a development gap between a photoconductor of an image-receiving module and a developer roller of a developer unit includes a image-receiving module frame, and at least a photoconductor support bar. The photoconductor support bars are combined on the image-receiving module unit frame. Each of the photoconductor support bars has a raised curved surface. The developer unit has at least a toner cartridge disposed corresponding to the curved surfaces. The distance between the toner cartridges is maintained by the photoconductor support bars supporting the photoconductor. The developer unit further includes a roller gap controlling apparatus to improve a gap accuracy of positioning the developer roller.
