摘要： An image forming apparatus is provided with a function for forming an image on a recording medium such, as a sheet or the like. The image forming apparatus includes an image forming unit for forming an image on a recording material including an image bearing member. A developing unit develops an electrostatic image formed on the image bearing member by a developer. A density detection unit detects a developer density inside the developing unit. The density detection unit detects a parameter relating to physical property of the developer based on a previous detection value detected by the density detection unit during a previous image forming drive operation by the image forming unit and before the previous image forming drive operation stops. The detection unit also detects a next detection value detected by the density detecting unit after the previous image forming drive operation stops and before a next image forming drive operation by the image forming unit starts. Accordingly, the image forming condition of the next image forming drive operation is controlled to be variable by a control unit based on the detection values.

摘要： A strobe camera with a strobe emission section movable between a first position in which strobe light can be emitted and a second position different from the first position. A strobe state detection unit outputs a first strobe state signal when the strobe emission section is in the first position, and a second strobe state signal when the strobe emission section is in the second position. A camera state detection unit outputs a first camera state signal when the camera is in a photographing-permitted state, and a second camera state signal when the camera is in a photographing-prohibited position. A control unit causes the camera to execute a warning operation when the camera state detection unit outputs the first camera state signal and the strobe state detection unit outputs the second strobe state signal, and causes the camera to stop execution of the warning operation and perform an exposure operation when the first strobe state signal is output instead of the second strobe stage signal.
