摘要:
A color image forming apparatus which is capable of preventing deterioration in image formation quality caused by vibrations of a developing unit without halting an image forming operation and using a simple construction. A developing rotary unit incorporates developing devices corresponding to respective ones of a plurality of image formation colors. In forming an image, the developing rotary unit is moved to location for development of an image of each of the plurality of image formation colors. The level of vibrations applied to the developing rotary unit is detected, and the drive control pattern for the developing rotary unit is determined depending on the detected level of vibrations.

An image forming apparatus capable of preventing degradation of image quality and reducing time required for rotational phase control. Toner images different in color are formed on a plurality of photosensitive drums, respectively. The toner images are transferred onto an intermediate transfer belt in superimposed relation. A motor controller performs phase control for bringing phases of the respective photosensitive drums into predetermined relation based on a rotational phase difference detected using phase detection sensors. When the rotational phase difference is out of a predetermined range, the motor controller performs the phase control with the photosensitive drums and the intermediate transfer belt separated from each other, whereas when the rotational phase difference is within the predetermined range, the motor controller performs the phase control with the photosensitive drums and the intermediate transfer belt in contact with each other.

An electromagnetic contactor has a contact device having a pair of fixed contacts and a movable contact; and an electromagnet unit including an exciting coil driving a movable plunger connected through a connecting shaft. The contact device is configured such that L-shaped portions have a contact portion formed in the pair of fixed contacts fixed maintaining a predetermined interval, and two ends of the movable contact are disposed to be capable of contacting to and separating from the contact portions of the L-shaped portion on a side opposite to that of the electromagnet unit. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger having a leading end protruding through an aperture formed in the magnetic yoke and urged by a return spring, and a ring-form permanent magnet magnetized in a movable direction of the movable plunger and fixed to enclose a peripheral flange portion.

The invention is to provide a miniaturized sheet processing apparatus in that a conveying length a conveying distance need not be increased even though the number of sheets per bundle increases. A glue applying bookbinder that partially glues sheets and performs a pressing process to form a sheet bundle. The glue applying bookbinder includes a processing tray that stacks sheets, a glue applying portion that applies a glue on the sheets on the processing tray, and pressing portions that press the sheets on the processing tray. The glue applying portion is arranged such that the glue applying portion can be moved from a first standby position outside the sheets stacked on the stacking portion to a second standby position, different from the first standby position, outside the sheets through an upper surface of the sheets, and the pressing portions are moved integrally with the glue applying portion.
