초록 ▼

Image forming equipment, which includes a developing device for supplying toners to the surface of a photosensitive member and developing a latent image on the surface of the photosensitive member to thereby form a toner image; a cleaning device for removing and collecting residual toners adhered to the surface of the photosensitive member after the toner image formed by the developing device is transferred to paper; a toner delivery device interposed in a closed loop between the developing device and cleaning device for delivering part of the surplus toners that have not been used for development in the development device to the cleaning device and for delivering the residual toners collected by the cleaning device to the developing device; and a toner tank for supplying toners to a toner delivery path R of the toner delivery device, is provided. In the image forming equipment, by providing a detection system for detecting the depletion of the toners with respect to the toner delivery path, the residual quantity of toners can be detected positively without increasing the size of the developing device.

대표청구항 ▼

Image forming equipment, comprising: a developing device, in contact with a photosensitive member, supplying toners onto a surface of said photosensitive member and developing a latent image on said surface of said photosensitive member, thereby forming a toner image; a cleaning device, disposed downstream from said developing device in sliding engagement with said photosensitive member, that removes and collects residual toners adhered to said surface of said photosensitive member after said toner image formed by said developing device is transferred to paper; a toner delivery device, interposed in a closed loop between said developing device and said cleaning device, delivering a portion of surplus toners not used for development in said developing device to said cleaning device, and delivering said residual toners collected by said cleaning device to said developing device; toner supply means for replenishing toners to a toner delivery path in said toner delivery device; and a detection device, disposed along said toner delivery path, detecting toner depletion.
