Abstract: An image forming unit detachably mountable to a main body of an image forming apparatus, the image forming unit comprising a first unit including an image bearing member, a second unit including an intermediate transfer member to which transferred is a toner image on the image bearing member, wherein the toner image on the intermediate transfer member is transferred to a recording material, and at least either of the first and second units is detachable from and attachable to the image forming unit.

Abstract: An image forming unit is detachably mountable to a main body of an image forming apparatus and includes a first unit including an image bearing member, and a second unit including an intermediate transfer member to which is transferred a toner image on the image bearing member. The toner image on the intermediate transfer member is transferred to a recording material, and at least either of the first and second units is detachable from and attachable to the image forming unit.

Abstract: The present invention relates to an image forming apparatus including an image carrier unit having an image carrier for carrying an image and a transfer material carrier unit having a transfer material carrier for carrying a transfer material, the transfer material carrier unit being capable of assuming a first state when the image on the image carrier is transferred onto a transfer material carried by the transfer material carrier and a second state that the transfer material carrier unit escapes more than the first state. The image carrier unit is detachably attached to an apparatus body through a space formed in the apparatus body after the transfer material carrier unit enters in the second state.

Abstract: The present invention relates to animage forming apparatus which has an image bearing body, a transferring portion for transferring an unfixed image on the image bearing body onto a recording material while conveying the recording material, a fixing portion for fixing the unfixed image onto the recording material while conveying the recording material having the unfixed image transferred in the transferring portion, flexure detecting device for detecting flexure of the recording material between the transferring portion and the fixing portion, recording material detecting device for detecting presence/absence of the recording material on a downstream side of the fixing portion with respect to a conveying direction of the recording material, and control device for controlling a convey velocity of the recording material in the fixing portion on the basis of a time from the detection of the recording material detected by the recording material detecting device to the detection of the flexure of the recording mat

Abstract: An object of the present invention is to provide an image forming unit detachably attachable to an image forming apparatus, which has an image bearing body, charging device for charging the image bearing body, a first unit having the image bearing body and the charging device, an intermediate transferring body, transferring device for transferring a toner image on the image bearing body to the intermediate transferring body, and a second unit having the intermediate transferring body and the transferring device, wherein one of the first unit and the second unit is supplied with electric power through the other unit.

Abstract: An image forming unit detachably mountable to an image forming apparatus includes an image bearing member, and an intermediate transfer member to which a toner image on the image bearing member is transferred, the image bearing member and the intermediate transfer member being movable relative to each other in the image forming unit.

Abstract: An image forming unit detachably mountable to a main body of an image forming apparatus, the image forming unit comprising a first unit including an image bearing member, a second unit including an intermediate transfer member to which transferred is a toner image on the image bearing member, wherein the toner image on the intermediate transfer member is transferred to a recording material, and at least either of the first and second units is detachable from and attachable to the image forming unit.

Abstract: An image forming apparatus has an image bearing member unit with a rotatable image bearing member for holding an image, and an intermediate transfer member unit with a rotatable intermediate transfer member unit to which image on the image bearing member is transferred, the image transferred to the intermediate transfer member unit being transferred to a transfer material so that, the image bearing member unit and intermediate transfer member unit are detachable from a main body of the image forming apparatus in a direction perpendicular to a rotational axis of the image bearing member and the intermediate transfer member unit.

Abstract: An image forming apparatus has a first unit with an image bearing member for bearing an image, a second unit having a transfer device for transferring the image on the image bearing member onto a transfer material, the second unit being rockable around a rock center to engage with and disengage from the first unit and having a positioning portion to be positioned at a predetermined position of the first unit, and a shifter for permitting a shifting movement of the rock center so that the positioning portion is positioned at the predetermined position even when a relative position of the first unit with respect to an apparatus body of the image forming apparatus is changed.

Abstract: An image forming apparatus has an apparatus body and an optional cassette feeder unit which is detachably mounted on the apparatus body. The optional cassette feeder unit stores sheets and feeds sheets to the image forming section of the body. The image forming apparatus is provided with locking sections which engage with leg sections provided at the lower surface of the apparatus body in order to connect the body to the optional cassette feeder unit.

Abstract: A sheet supplying device having a sheet support for supporting sheets, a sheet supply provided in a laterally deviated position with respect to the sheet supplying direction for supplying sheets supported by the sheet support and a stacking reference guide for impinging on a lateral end of the sheets supported by the sheet support to thereby define the position of the sheets. The guide defining the position of the sheets is supported by the sheet support in such a manner that the sheets are supported in a state inclined by a predetermined angle with respect to the sheet supplying direction.
