    Abstract: A rotary developing device 30 is provided in an image forming device that is rotated by an input gear 46. The rotary developing device 30 has a plurality of developing units 13, a frame 28, and a rotation stop mechanism 50. Each of the plurality of developing units 13 house toner of one of the colors, and develops at a predetermined developing position. The frame 28 includes a support portion 36 that supports the plurality of developing units 13 and has a rotation shaft, and a ring shaped gear 29 that is rotated by the input gear 46. The rotation stop mechanism 50 stops the rotation of the frame 28 at the developing position. Also, the number of gear teeth in the ring shaped gear 29 is the number of gear teeth in the input gear 46 multiplied by the number of developers.

    Abstract: In a printer, three toner patches are primary-transferred successively to an intermediate transfer belt. Here, after the first toner patch passes through a belt cleaner and before the second toner patch reaches the belt cleaner, and after the second toner patch passes through the belt cleaner and before the third patch reaches the belt cleaner, the belt cleaner is operated to change the state of contact to the intermediate transfer belt to a different state. A density sensor detects density of the toner image on the intermediate transfer belt, and presence/absence of the toner patch is detected. When presence/absence of the first to third patches is detected alternately, it is determined that the belt cleaner is performing the operation described above.

    Abstract: An image forming apparatus appropriately adjusts an image forming conditions even if a halftone-processed image data is inputted. The image forming apparatus forms a patch image by applying a halftone process which is substantially equivalent to the halftone process which has been previously performed for the inputted image data. The image forming apparatus detects the density of the formed patch image and adjusts the image forming conditions according to the detected density.

    Abstract: An image forming apparatus adapted for a smooth mounting/dismounting of a process unit and for the reduction of wasteful power consumption is provided.Unless a new image signal is applied after completion of an image forming operation, the apparatus starts a clocking operation by an internal timer (Step S101). If the apparatus is left standstill for a predetermined length of time (Step S102), a sleep process (Step S103) is executed to shift the apparatus to a power save mode to consume less power. When an outside cover is opened (Step S105), on the other hand, the apparatus is shifted to a replacement operation mode (Step S106) in which only the rotation of a development rotary is permitted. However, if the apparatus is left with the outside cover opened (Step S108), the sleep process is executed.
