Image forming apparatus

The invention relates to the technical field of imaging, and discloses imaging equipment. The imaging equipment comprises a main body and an upper cover, the main body comprises a containing cavity, and the upper cover is rotationally connected with the main body to open or close the containing cavity; the imaging equipment further comprises a first transmission assembly, and a second transmission assembly, a first axial cam, a first driving shaft and a photosensitive drum which are positioned in the accommodating cavity. The upper cover is connected with the second transmission assembly through the first transmission assembly, and when the upper cover opens or closes the containing cavity, the second transmission assembly is driven by the first transmission assembly to move horizontally in the first direction. The second transmission assembly is combined with the first axial cam to drive the first axial cam to rotate around a first axis extending in the second direction, so that the first driving shaft is driven to move between a first position and a second position in the second direction; at the first position, the first driving shaft is combined with the photosensitive drum; at the second position, the first driving shaft is separated from the photosensitive drum, and the first direction is perpendicular to the second direction. The transmission stability is improved.
