An image forming apparatus includes an image carrier, a developer carrier disposed so as to face the image carrier, a transfer body disposed so as to face the image carrier, and a contact-separation mechanism. The contact-separation mechanism brings the developer carrier and the image carrier into contact with each other and separates the developer carrier and the image carrier from each other, and brings the image carrier and the transfer body into contact with each other and separates the image carrier and the transfer body from each other.

Image forming apparatus with contact-separation mechanism for image carrier

An image forming apparatus includes an image forming apparatus main body, and a replaceable part detachably attached thereto. The replaceable part is moveable in a first direction to be attached to the image forming apparatus main body and in a second direction to be detached from the image forming apparatus main body. The replaceable part includes a storage portion. The storage portion including a memory for storing information of the replaceable part and/or the image forming apparatus main body, and a first electrically-conductive contact portion electrically connected to the memory. The image forming apparatus main body includes a second electrically-conductive contact portion that electrically contacts the first contact portion, and a supporting portion that supports the second electrically-conductive contact portion. The second electrically-conductive contact portion has a first end portion fixed to the supporting portion and a second end portion which is movable with respect to the supporting portion. The first electrically-conductive contact portion includes an inclined surface contacting the second electrically-conductive contact portion. The inclined surface faces the first direction and is inclined at a predetermined angle with respect to the first direction.

Image forming apparatus that ensures an electrical connection between a replacement part and a main body part of the apparatus

A developing device that is provided in an image forming device that forms an image includes an image carrier on which an electrostatic latent image is formed; a developer carrier that is configured to form a developer image on a surface of the image carrier by attaching developer on the electrostatic latent image; and a contact member that is configured to contact the developer carrier. The contact member contacts the developer carrier and exerts a contact pressure per unit area thereon, the contact pressure per unit area being based on charging characteristics of the developer being used.

An image forming apparatus includes an image forming apparatus main body, and a replaceable part detachably attached to the image forming apparatus main body and movable in attaching-and-detaching direction to be attached to or detached from the image forming apparatus main body. The replaceable part includes a storage portion, the storage portion including a memory for storing information of the replaceable part and/or the image forming apparatus main body, and a first contact portion electrically connected to the memory. The image forming apparatus main body includes a second contact portion that electrically contacts the first contact portion. The first contact portion has an inclination at a predetermined angle with respect to the attaching-and-detaching direction.

The present invention aims to synthesize a polypeptide having an unnatural structure at the N-terminus via a biosynthetic process by translation of amino acid sequence information encoded by a nucleic acid. A polypeptide having any amino acid at the N-terminus is synthesized by using an ARS ribozyme that catalyzes the acylation of tRNA with any amino acid to attach any amino acid to an initiator tRNA, thereby initiating a translation with the initiator tRNA.

A developing device that is provided in an image forming device that forms an image includes an image carrier on which an electrostatic latent image is formed; a developer carrier that forms a developer image on a surface of the image carrier by attaching a developer on the electrostatic latent image; a supplying member that supplies the developer to the developer carrier by contacting the developer carrier, and that scrapes the developer remaining on the surface of the developer carrier from the developer carrier, and a deformation amount between the developer carrier and the supplying member is individually configured corresponding to a location where the developing device is provided in the image forming device.

A developer storage apparatus includes a developer receiving opening for receiving a developer, a developer conveying unit disposed below the developer receiving opening and having a first conveying member that conveys the developer in a conveying direction, a developer detection unit for detecting the developer, and a wall surface portion provided on a downstream side of the developer detection unit in the conveying direction.

Developer storage apparatus, developer cartridge, developing device and image forming apparatus

A developer storing body is detachably attached to an image forming unit main body of an image forming unit. The developer storing body includes a cartridge main body for storing a developer. The cartridge main body has a developer outlet opening through which the developer is ejected. The developer storing body includes an outlet shutter member movable with respect to the cartridge main body so as to open and close the developer outlet opening. A movable direction of the outlet shutter member is substantially the same as a direction in which the developer storing body is attached to or detached from the image forming unit main body.

A developer storing container includes a developer storing portion having a developer outlet opening at a substantially longitudinal center portion, and an agitation member rotatable about a rotation axis to thereby agitate and eject the developer via the developer outlet opening. The agitation member includes a mounting portion with a mounting surface along the rotation axis, and an elongated flexible member having first and second ends. The flexible member is mounted to the mounting portion at the first end so that the second end defines a sliding end portion at which the flexible member slides in a sliding direction. Both longitudinal end portions of the sliding end portion of the flexible member slide along the inner surface of the developer storing container, ahead of a substantially longitudinal center portion of the sliding end portion in the sliding direction, and are inclined with respect to a direction perpendicular to the sliding direction.

A development device includes a plurality of development units and a waste substance container or containers storing the waste substance removed by the cleaning member. Each of the plural development units includes an image carrier carrying a developer image formed by developer and a cleaning member cleaning the image carrier by removing a waste substance. A number of the waste substance containers disposed is smaller than a number of development units disposed, and the number of the waste substance containers is greater than or equal to one.

Development device and image forming apparatus

An exchange unit to be detachably attached to an image forming apparatus includes an information holding unit for communicating with a communication unit disposed in the image forming apparatus to read or write information; a storage unit for retaining the information holding unit; a housing unit having an opening portion for inserting the information holding unit into the storage unit; and a lid member for opening and closing the opening portion.
