A detachable unit to be attached to a unit-receiving apparatus includes a unit body, a rotary member, an urging member urging the rotary member toward a downstream side in a detachable-unit-attaching direction, a contact-receiving portion provided on the rotary member, first and second support-receiving portions provided at respective ends of the rotary member, first and second supports provided at respective positions of the unit body corresponding to the positions of the first and second support-receiving portions, and first and second rotary support members provided between the first support-receiving portion and the first support and between the second support-receiving portion and the second support, respectively, and supporting the respective ends of the rotary member such that the rotary member is rotatable. The first and second rotary support members are supported in such a manner as to be movable in a detachable-unit-attaching-and-detaching direction.

This invention relates to a cleaning unit including a cleaning blade that keeps a front end of rubber material in contact with the surface with a pressure so as to scrape residual toner left on the surface of the photoreceptor and a fiber body having multiple fibers in contact with the surface of the photoreceptor in the upstream in the cyclic moving direction of the surface of the photoreceptor with respect to the cleaning blade, the cleaning blade satisfying A≧−2.5×B+102 and 6.3≦B≦19.6, where A designates a contact angle (°) with pure water under 23° C., 55% RH and B designates 100% modulus (MPa) at 23° C.
摘要:
In an image forming apparatus adapted to transfer a toner image formed on a photosensitive drum to an intermediate transfer belt, and thereafter to a sheet, the position of one end portion of a backup roll around which the intermediate transfer belt is passed is set regulatable, this end portion being fixed after the position thereof has been regulated. The position of one end portion of a driving roll, cleaning blades or photosensitive drum may be set regulatable. This arrangement enables the skew of an image formed on a sheet to be reduced.

The developer delivering device includes a first delivering path, a second delivering path, a helical delivering blade disposed in the second delivering path, and a developer breaking member disposed in a connecting portion of the first delivering path and the second delivering path. The developer breaking member includes a breaking portion disposed opposite to a side wall of the second delivering path in a developer delivering direction of the second delivering path, a contact portion that is in contact with the helical delivering blade and extended in the developer delivering direction between the breaking portion and a center of the rotation of the helical delivering blade, and a coupling portion. The breaking portion has a first breaking portion and a second breaking portion. The contact portion has a first contact portion and a second contact portion. The coupling portion couples the first contact portion to the second contact portion.

摘要:
An apparatus and techniques for reducing the electrostatic sticking of a transfer member to the image carrying body of an image forming apparatus. The visible image on the image carrying body is formed by charged participles. A collective transfer unit collectively transfers the visible image from the image carrying body to a transfer member. A transfer member judging unit judges whether a transfer member exists downstream of and in the vicinity of a transfer position of the collective transfer unit. A pre-stop processing unit for preventing, if the transfer member presence judging unit judges that a transfer monitor exists when the stopping unit stops the device, the transfer member from electrostatically sticking to the image carrying body.

A collection device includes: a collection container that collects output material; a storage box that is opened upward to store a lower part of the collection container; and a support member that is fixed to a housing and supports the storage box so that the collection container is stored in the storage box and is freely drawn to the outside of the housing. The collection container includes a handle located frontward in a pulling direction and at an upper part of the collection container. The storage box includes a notch formed in a rear surface in the pulling direction. When the handle of the collection container is pressed backward in the pulling direction, a part of the collection container, which part is located backward in the pulling direction, protrudes from the storage box through the notch, so that the collection container inclines backward in the pulling direction.
