<p>PROBLEM TO BE SOLVED: To provide a developing device and an image forming device which can prevent damage, etc., effectively caused by a pulverized toner being supplied accidentally. SOLUTION: For a linking gear 45, a first intermediate gear 46, a second intermediate gear 47 of a transmission mechanism 45 provided in a development cartridge and a development roller gear 49, a small module is selected, and each of these gears is composed so as to be made to tooth-jump or to slip when driving force of 1.55 times or more of the driving force for development performed by a polymerized toner occurs. Even when the pulverization toner is accidentally supplied, thereby, the damage to each part, such as the developing roller 22 caused by it, is prevented.</p> |
