摘要： A fixing device includes a first rotating body, a second rotating body, a frame, a shutter, a pressure arm, a cam, a shutter arm, and an arm cam. The shutter is rotatable about a first axis between a closed position and an open position. The pressure arm presses the first rotating body against the second rotating body. The cam is rotatable about a second axis and pushes the pressure arm. The shutter arm is connected to the shutter and rotates about the second axis independent of the cam, to cause the shutter to rotate between the closed position and the open position. The arm cam rotates about the second axis to push the shutter arm at a position offset from the second axis and cause the shutter arm to rotate about the second axis.

摘要： An image-forming apparatus includes: a main casing; a drawer movable in a first direction between a first position inside the main casing and a second position outside the main casing; process cartridges attachable to and detachable from the drawer; a controller; and a device-side terminal connected to the controller. The process cartridges are arranged in the first direction in an attached state to the drawer. Each process cartridge includes a photosensitive drum, a magnetic roller, a developing container for storing carrier, a conveying member, a toner sensor, a process memory, and a process-side terminal. The toner sensor is configured to output a detection signal corresponding to a concentration of toner in the developing container. The process-side terminal is for both outputting the detection signal of the toner sensor and outputting information about the process cartridge stored in the process memory. The device-side terminal is configured to contact the process-side terminal.

摘要： To provide an image forming device that can effectively predict a replacement timing of a photoconductor drum. A toner image is to be formed on the photoconductor drum. The charger is configured to charge the photoconductor drum. The potential sensor is configured to measure a charge potential of the photoconductor drum. The memory stores a manufacturing date of the photoconductor drum and a failure threshold value of the charge potential related to a failure of the photoconductor drum. The processor is configured to calculate an elapsed time from the manufacturing date based on the manufacturing date, update the failure threshold value based on the elapsed time, and predict a replacement timing of the photoconductor drum based on the updated failure threshold value.
