图像形成装置
摘要：
本发明提供一种图像形成装置。本发明的图像形成装置具备图像形成装置主体、第一驱动机构、第一驱动单元、图像承载体、显影装置和偏压部件。第一驱动单元具有输入部，从第一驱动机构向该输入部传递旋转驱动力。显影装置相对于图像形成装置主体能够装卸。偏压部件将显影装置向图像承载体侧偏压。所述显影装置具有向所述图像承载体上供给调色剂的显影辊和收纳并支撑显影辊的显影部。在显影辊的轴向的一端部设置有第一驱动单元。显影部被偏压部件偏压，从而摆动以接近图像承载体。显影部相对于第一驱动单元能够摆动。根据本发明，提供一种能够抑制显影间隙在显影辊的两端部不同的图像形成装置。
摘要（英）：

An image forming apparatus (1) includes an image forming apparatus body (3), a first driving mechanism (51), a first drive unit (30), an image carrier (8), a developing device (2), and a biasing member (11). The first drive unit includes an input unit (31) to which a rotary drive power is transmitted from the first driving mechanism. The developing device is removably attachable to the image forming apparatus body. The biasing member biases the developing device toward the image carrier side. The developing device includes a developing roller (20) supplying toner onto the image carrier, and a developing unit (22) housing and supporting the developing roller. The first drive unit is located at one end portion in an axial direction of the developing roller. The developing unit swings to come close to the image carrier by the biasing member biasing the developing unit. The developing unit is swingable with respect to the first drive unit.
