ABSTRACT:
A guiding member is disposed at a frame upstream of a transfer roller in a conveying direction, thereby guiding a recording medium to a transfer position. The guiding member has front and back surfaces. A guiding portion of the guiding member is configured to contact the recording medium for guiding the recording medium to the transfer position. The base portion is positioned upstream of the guiding portion in the conveying direction. The base portion is formed with at least one through-hole having an inner edge. The frame includes a supporting portion and a protruding portion. The supporting portion is configured to contact the back surface of the guiding member, thereby supporting the guiding member. The protruding portion protrudes through the at least one through-hole and engages with the inner edge, thereby fixing the base portion of the guiding member to the frame.
