    摘要: A development device includes a development casing, a developer bearer disposed facing a latent image bearer through an opening formed in the development casing, a magnetic field generator, a developer regulator disposed facing the developer bearer, a first seal member to cover a clearance between the latent image bearer and a rim of the development casing upstream from the opening, and a second seal member. The first seal member includes a first end portion fixed to the rim of the development casing and a second end portion in contact with the latent image bearer, and the second seal member includes a first end portion fixed to an inner face of the development casing farther from the latent image bearer than the first seal member, and a second end portion hanging to contact the developer carried on the developer bearer downstream from the developer regulator.

    摘要: A collapsible lens barrel includes a first holding frame (2) for holding a first lens group (L1), a second holding frame (5) for holding a second lens group (L2) that is disposed on an image plane side with respect to the first lens group (L1), an actuator (6) for moving the second holding frame 5 in an optical axis direction, and a tubular cam frame (17) including a plurality of cam grooves that are formed at substantially equal intervals around a circumferential direction for moving the first holding frame (2) in the optical axis direction. The actuator (6) is attached to a portion in the cam frame (17) where the cam grooves are not formed. The first lens group (L1) is moved using the cam grooves, and the second lens group (L2) is moved using the actuator (6), so that a faster zooming speed and a lower zooming noise can be achieved.

    摘要: An image forming system includes an image forming apparatus that includes process units for different colors and a lifetime management device that manages lifetime information on each unit of the image forming apparatus. The lifetime management device counts the number of prints produced by the image forming apparatus with respect to each of photoconductor units and developing units in the process units, and measures an operation amount unique to the respective units. Based on the number of prints, service life of each unit and operation amount, the lifetime management device calculates the remaining lifetime of each unit.

    摘要: A cam pin (16) and a demating prevention pin (35) that are provided in a driving frame (15) and have an identical shape are allowed to mate with a cam groove (18) and a demating prevention groove (36) that are provided in a cam frame (17), respectively. A first protrusion (37) is provided on at least one side in an optical axis direction of a portion of the demating prevention groove (36) with which the demating prevention pin (35) mates when the driving frame (15) is advanced. When an external force is applied to the driving frame (15), a cylindrical portion (35f) of the demating prevention pin (35) and the first protrusion (37) come into contact with each other. This prevents the cam pin (16) from demating from the cam groove (18). The cam pin (16) and the demating prevention pin (35) are made of common components, making it possible to reduce the number of components.
