摘要： In an image forming apparatus, a computing unit computes phase shift amounts A(i) for every correction relative phase angle θ(j) based on an amplitude B of a reference compressional wave αa, an amplitude C(i) of a detection compressional wave α(i), and a relative phase angle φ(i). A setting unit specifies the phase shift amounts A(i), and sets a correction relative phase angle θ(j) corresponding to the specified phase shift amounts A(i). A correction unit corrects, based on the correction relative phase angle θ(j) set by the setting unit, a relative phase shift between a periodic variation in the circumferential speed of a first image bearing member and a periodic variation in the circumferential speed of a second group image bearing member by operationally controlling at least one of first and second drive units.

摘要： An image forming apparatus includes a controller for detecting the opening and closing of a shutter from the output from an optical sensor and controlling the opening and closing operation of the shutter based on the detected result. The controller determines that if the optical sensor is turned “ON” within a predetermined period of time from when the shutter begins opening, the operation of the shutter from the closed state to the open state is correctly detected. When no reflected light is detected by the optical sensor even after a predetermined time has elapsed, the controller determines that an anomaly has occurred and closes the shutter and repeat another detecting process.
