摘要： A developing device includes a main body that is arranged between a pair of supporting members and includes a developing roller. Both end portions of the developing roller are supported by the supporting members in a first direction in which the developing roller is movable toward and away from an image carrier. A groove is formed on each of the supporting members. Either one of an end portion of the developing roller and a bearing that supports the end portion is inserted into the groove. Either one of at least one of the end portions of the developing roller and at least one of the bearings is movable in the groove in a second direction that intersects the first direction.

摘要： A toner transport screw that is capable of maintaining a smooth and stable transport function. The toner transport screw, in which a helical blade is disposed on the circumference of a rotating shaft, has at least one spiral direction reversal part formed by connecting the respective ends of a first blade part and a second blade part, the directions of spiral of the first blade part and the second blade part being in opposite directions. A passage, which allows the toner to pass through the blades in the circumferential direction of the rotating shaft, is formed in the spiral direction reversal part.

摘要： In a toner collecting device of the present invention for conveying collected waste toner to a waste toner storing portion with a toner conveying device, the toner conveying device is positioned at a side opposite to a driveline included in an apparatus body to which the toner collecting device is mounted. A driveline for driving the toner conveying device is not arranged at the side opposite to the driveline of the apparatus body, but the toner conveying device is directly driven by the driveline of the apparatus body. With this configuration, the toner collecting device is capable of driving, e.g., a toner conveying belt or a toner conveying screw arranged at the counter drive side without sophisticating the configuration.

摘要： An image forming apparatus includes an exposure device as a light source, a developer container storing developer and attached to a main body of the image forming apparatus perpendicular to a lengthwise direction of the photoconductor, a developing unit and a photoconductor unit having a photoconductor for bearing a latent image thereon each detachably attached to the main body substantially in the same direction as the developer container. An exposure device displacing mechanism displaces the exposure device between a first position enabling the exposure device to function as the light source and a second position disabling the exposure device to function as the light source. The photoconductor unit is detached when the developer container is either displaced from an initially attached position or is removed from the main body and the exposure device displacing device has displaced the exposure device to the second position.
