摘要： An image forming apparatus includes a transfer belt onto which a toner image formed on an outer surface of a photosensitive medium is transferred. The transfer belt moves along a predetermined closed path while being supported by a plurality of rollers. A protection unit protects the transfer belt by being attached to at least one of an inner surface and an outer surface of a non-transferring region of the transfer belt. A control unit controls the transfer belt so that an overlapping part where the protection unit is attached to the transfer belt, and a seam part where two ends of the transfer belt are connected stops at a predetermined location after printing. The image forming apparatus substantially prevents partial loss of an image by preventing wrinkles in the transfer belt.

摘要： An image forming apparatus for determining a state of conveying a printing medium and a method thereof are disclosed. The image forming apparatus includes a convey belt rotating in a caterpillar manner for conveying a printing medium to a photoconductor. A charge roller charges a printing medium that enters the convey belt. A convey roller faces the charge roller and forms a convey nib with the charge roller. A transfer unit transfers a developer image formed on the photoconductor to the printing medium. A resistance detector constantly detects resistance of the convey roller. A controller determines whether the resistance is varied within a reference time.
