Patent ID: 8139996

Claim:
An electrophotographic image forming device that forms images on recording sheets, the image forming device comprising: a frame having an opening; a cover movable for opening and closing the opening; a drum unit disposed in the frame and having a plurality of photosensitive drums each defining an axis, the plurality of photosensitive drums being juxtaposed in line in a direction orthogonal to the axis; a belt unit accommodated in the frame and having a plurality of rollers and an endless belt mounted over the plurality of rollers under tension, the endless belt having a first running part running in a sheet conveying direction and in direct confrontation with each of the photosensitive drums, the first running part extending in a first direction, the drum unit being movable in the first direction and accessible through the opening; a pair of registration rollers that nips the recording sheets therebetween to correct skew in the recording sheets and to convey each recording sheet toward the belt unit, the pair of registration rollers being supported to the frame and disposed at a side opposite to the drum unit with respect to an imaginary plane which is an extension of the first running part, the pair of registration rollers defining a nip point therebetween where the recording sheet is nipped, the nip point being located at a position aligned with the belt unit in an extending direction of the belt unit; a first guide that guides the recording sheets conveyed from the pair of registration rollers toward the endless belt, the first guide having a guide portion located on a side the same as that of the drum unit with respect to the imaginary plane for allowing a leading edge of the recording sheet to direct toward the endless belt at the side the same as that of the drum unit; and a second guide positioned in confrontation with the first guide for guiding the recording sheets conveyed from the pair of registration rollers toward the endless belt in cooperation with the first guide, wherein the pair of registration rollers provides a circumferential speed greater than a running speed of the endless belt.
