Abstract
An image forming apparatus having a photosensitive member unit, a development unit, and a toner recycling mechanism including a toner feed device. The photosensitive member unit includes a photosensitive member, and an electrostatic latent image forming device and a cleaning device disposed around the photosensitive member. The photosensitive member unit and the development unit are separately mounted in a main body of the apparatus to form an image forming section. The toner feed device is detachably connected between the front sides of the photosensitive member unit and the development unit, the toner collected by the cleaning means is transported to the development unit to perform recycling when the toner feed device is connected, and the photosensitive member unit and the development unit can be independently dismounted from the apparatus body when the toner feed device is detached. The toner feed device is automatically detached when the development unit is dismounted from the apparatus body.
