    摘要： Disclosed herein are a discharge device of an image forming apparatus, an image forming apparatus having the same, and a control method thereof, which prevents jamming or loading defects of paper to be discharged. To this end, a press force adjusting device is provided to adjust a press position of an elastic press member upward or downward. The press force adjusting device includes a press plate to support the elastic press member and a height adjustor to adjust a height of the press plate. The height adjustor adjusts the height of the press plate via rotation of a cam body having an eccentric rotation center. The height adjustment enables adjustment in the curling degree of paper depending on a paper thickness or environment conditions.

    摘要： The invention relates to a supported metallocene catalyst composition and a process for the preparation of polyolefin using the same. A supported metallocene catalyst composition according to the invention is prepared by bringing a compound of a group IV transition metal into contact with an inorganic or organic porous carrier treated with an ionic compound. Advantages of a supported metallocene catalyst composition of the invention include an increase in the catalyst activity during polymerization of slurry and an olefin compound in the vapor phase even at a low content of metallocene metal components within the carrier, and an improvement in solving process problems such as fouling, sheeting, plugging or the like.
