The developing-unit attachment section receives a first developing unit having plural developing members or a second developing unit having a single developing member. The transfer-unit attachment section receives a first transfer unit, which includes a first transfer member capable of retaining a recording medium and a first transfer driving unit that rotates the first transfer member, and a second transfer unit, which includes a second transfer member that cannot retain the recording medium. When the first developing unit and the first transfer unit are attached to the developing-unit attachment section and the transfer-unit attachment section, respectively, the first transfer driving unit is mechanically connected to the first developing unit.

Image forming apparatus and transfer device having attachable developing unit

An image forming apparatus includes an image carrying member, a transfer member, a leading-end holding member, and a trailing-end holding member. The leading-end holding member is mounted on the transfer member and holds, on an outer peripheral surface of the transfer member, a leading-end portion of a recording medium fed to a sheet feeding position that is further upstream than a transfer position in a rotation direction of the transfer member. The trailing-end holding member rotates along the outer peripheral surface. The trailing-end holding member presses the recording medium against the outer peripheral surface while waiting at a waiting position that is further upstream than the transfer position and downstream than the sheet feeding position, and holds a trailing end portion on the outer peripheral surface while rotating together with the transfer member when the trailing end portion of the recording medium arrives at the waiting position.

Image forming apparatus with leading-end and trailing-end holding members to prevent sagging of recording medium during transportation

A transfer device includes a transfer body that transports a recording medium to a transfer position to transfer toner images to the recording medium; a leading-end gripping member that grips a leading-end portion of the recording medium when causing the recording medium to be wrapped around the transfer body and releases the leading-end portion when causing the recording medium that has been wrapped around the transfer body to become separated from the transfer body; and a moving member that moves, after a final toner image starts being transferred to the recording medium but before the leading-end gripping member releases the leading-end portion, the leading-end gripping member while the leading-end gripping member grips the leading-end portion in order to cause a leading-end side of the recording medium to become separated from the transfer body.

Transfer device and image forming apparatus

A conveyance mechanism includes a first conveyed material storage section and a second conveyed material storage section that respectively store a first conveyed material and a second conveyed material. When a position of the first conveyed material storage section is changed to a conveyed position where the first conveyed material is to be conveyed, a discharge destination of a discharge member is switched to a first conveyed material discharge section. When the position of the first conveyed material storage section is changed to an evacuation position evacuated from the conveyed position, the discharge destination of the discharge member is switched to a second conveyed material discharge section.

Conveyance mechanism for image forming apparatus with switchable store and discharge sections

In an image forming apparatus, the following inequalities (1) and (2) are satisfied:(L1&#x2212;L3)&#xd7;(V2/V1)&#x3c;L2&#x2003;&#x2003;(1)L2&#x3c;(L1&#x2212;L3+L4)&#xd7;(V2/V1)&#x2003;&#x2003;(2)

An image forming apparatus includes: an image carrier that is rotatably arranged and carries an image on an outer circumferential surface thereof; a transfer member that is rotatably arranged to face the image carrier and transfers the image carried on the image carrier onto a sheet held between the transfer member and the image carrier; a leading edge gripping member that is secured to the transfer member and grips a leading edge side of the sheet in a transport direction thereof on an outer circumferential surface of the transfer member; and a trailing edge holding member that is arranged to be rotatable around the transfer member, holds a trailing edge side of the sheet in the transport direction thereof between the trailing edge holding member and the outer circumferential surface of the transfer member, and bends to release the trailing edge side of the sheet in the transport direction thereof.

Image forming apparatus and transfer device

A developing device includes: a developer holding body including: a hollow development rotary body which is opposed to an image holding body capable of holding a toner image and has a smooth surface whose surface roughness is lower than or equal to 5 &#x3bc;m in terms of maximum height; and a magnet member which is fixedly housed in the development rotary body and in which a plurality of magnetic poles are arranged alongside its periphery, the developer holding body operating in such a manner that developer containing toner and carrier is held on the development rotary body by magnetic force produced by the magnetic poles of the magnet member as the development rotary body is rotated; a layer regulating rotary body as defined herein; and a development driving device as defined herein.
