摘要： A plurality of image bearing members is supported by an apparatus main body and is arranged in a predetermined direction. A belt unit is configured to be detachably mounted on the apparatus main body. The belt unit includes a belt frame, a plurality of belt support rollers, a belt, and a plurality of transfer members. The plurality of belt support rollers is supported by the belt frame. The belt is movably supported by the plurality of belt support rollers and extends in the predetermined direction. Each of the plurality of transfer members is disposed in confrontation with a corresponding one of the plurality of image bearing members with the belt interposed therebetween. A positioning member fixes, relative to the apparatus main body, each of the plurality of transfer members at a position in the predetermined direction when the belt unit is mounted on the apparatus main body.

摘要： The present invention provides an image-forming device having a developer-carrying member, an image-carrying member, a belt, and a cleaning unit. The developer-carrying member has an outer surface including a thin layer forming region for carrying a thin layer of developer. The thin layer forming region has a first width in a widthwise direction. The thin layer forming region includes an effective image forming region used for forming an image on a recording medium. The image-carrying member has a surface on which an electrostatic latent image based on the image is formed and developed into a developer image by the developer carried on the effective image forming region. The belt is configured to circulate in a moving direction orthogonal to the widthwise direction and transfer the developer image onto the recording medium. The belt has an outer surface including a cleanable region having a second width in the widthwise direction. The cleaning unit cleans the developer on the cleanable region. The second width is greater than the first width. The cleanable region is placed with respect to the thin layer forming region so that each widthwise end of the second width is positioned outside of each widthwise end of the first width in the widthwise direction.

摘要： A laser printer is detachably provided with a carrier belt, support rollers for supporting the carrier belt, and a belt unit provided with a belt frame. A unit support portion for supporting a bearing portion of the support roller and a unit support portion for supporting a bearing portion of the support roller are provided at a side of the main body of the apparatus. Urging by a coil spring allows the bearing portion to press the unit support portion against the support roller. An image forming unit that contains four process cartridges is detachably provided above the belt unit opposite to the belt. The belt unit may be removed from the main body by detaching the image forming unit.
