20130223878 | Image Forming Apparatus Having Developing Unit in Which Developing Device is Movably Disposed - An image forming apparatus includes: a main body; a photosensitive drum rotatably supported in the main body; a developing unit detachably accommodated in the main body in a direction along an axis of the photosensitive drum in a state where the photosensitive drum is disposed in the main body. The developing unit includes: a developer carrying member configured to carry developer for supplying the developer to the photosensitive drum; a developing frame supporting the developer carrying member; and a supporting assembly configured to support the developing frame such that, in a state where the developing unit is accommodated in the main body, the developing frame is movable between a proximity position where the developer carrying member and the photosensitive drum being positioned adjacent to or in contact with each other and a separation position where the developer carrying member and the photosensitive drum being separated from each other. | 08-29-2013 |
20120308273 | Image Forming Device Having Guide Mechanism for Guiding Transferring Unit - An image-forming device may include a main body, a developing unit, a transferring unit, and a tray. In some examples, the developing unit may include a developer-accommodating section that accommodates developer and a photosensitive member on which an electrostatic latent image is formed. The developing unit may further include a developer-carrying member to develop the electrostatic latent image. The tray may enable the developing unit to move between a contact position and a separate position. | 12-06-2012 |
20120027472 | Image Forming Device Having Belt Disposed Above Developing Unit - An image-forming device includes a main body; a developing unit; a transferring unit; and a tray. The developing unit has a developer-accommodating section that accommodates developer and a photosensitive member on which an electrostatic latent image is formed. The developing unit further has a developer-carrying member to develop the electrostatic latent image. The tray enables the developing unit to move between a contact position and a separate position. | 02-02-2012 |
20100209140 | Image-Forming Device with Holding Unit Having Multiple Positions - An image-forming device includes a main body; at least one photosensitive member; a plurality of developing units; and a transferring unit. Each developing unit has a developer-accommodating section that accommodates developer. Each developing unit further has a developer-carrying member. | 08-19-2010 |
20090028602 | Image-Forming Device - An image-forming device includes: a main body; at least one photosensitive member; a plurality of developing units; a transferring unit; a first holding unit; and a guiding unit. The photosensitive member has a support shaft. Each developing unit has a developer-accommodating section that accommodates developer. The developer-accommodating section has an opening in a top side thereof. Each developing unit further has a developer-carrying member that is disposed near the opening of the developer-accommodating section. The first holding unit holds the plurality of developing units that are arranged in a row along a first removal direction. The first removal direction is orthogonal to the support shaft of the photosensitive member. The first holding unit is accommodated at a first accommodating position in the main body. The guiding unit enables the first holding unit to move between the first accommodating position and a first removal position that is separate from the first accommodating position in the first removal direction. | 01-29-2009 |
