Abstract

The present invention provides a simple lock mechanism for fixing the position of a developing device when replenishing toner in a device that supplies toner to a developing device from a toner storage portion provided separately from the developing device through a toner replenishing member. As the developing rotary frame locking mechanism of the image forming apparatus, the solenoid (71) is disconnected, the spring (76) is used to move the lever (74) downward, the second member (72) rotates counterclockwise, and the claw at the top end The portion (72a) is engaged with the protrusion of the first member (99a). In this state, the rotating frame drive gear (99) is prohibited from rotating due to engagement of the claw portion (72a) with the protrusion of the first member (99a), that is, the rotating frame (15) is in a locked state. Therefore, the conventional two-way lock mechanism is not required, and positional deviation of the rotary frame during toner supply can be suppressed with a simple structure.

Description

technical field [0001] The present invention relates to an image forming device, especially an image forming device including a rotary developing device in which developing devices are arranged in a circumferential direction and held on a rotating frame, and a plurality of developing devices are rotated to face an image carrier respectively. Background technique [0002] In an image forming apparatus utilizing electrophotography, a charger, an exposure device, a developing device, a transfer device, a cleaning device, and the like are provided around a photosensitive drum serving as an image carrier. Also, a fixing device is provided on the downstream side of the transfer member of the photosensitive drum. In such an image forming apparatus, first, the surface of the photosensitive drum is also charged by a charger. Then, according to the image information, the photosensitive drum is exposed to light by an exposure device to form an electrostatic latent image on the surface...
