    Abstract: According to one embodiment, a fuser includes a heat roller, an endless belt, a first press roller and a second press roller. The heat roller rotates and contacts a toner surface side of a sheet, and heats the sheet. The endless belt contacts a part of an outer peripheral surface of the heat roller. The first press roller contacts a part of an inner peripheral surface of the endless belt, and is provided at an insertion part of the sheet in a nip portion where the heat roller contacts the endless belt. The second press roller contacts a part of the inner peripheral surface of the endless belt, is provided at an exit part of the sheet in the nip portion, and has a lower rotational resistance than the first press roller.

    Abstract: An image forming apparatus includes a photoreceptor, an exposure unit having a plurality of light emitting elements that are configured to emit light corresponding to an image to be formed towards the photoreceptor, a developing unit containing toner that is transferred to the photoreceptor therefrom, and a control unit configured to control a potential of the developing unit. The control unit is configured to control the potential of the developing unit, such that the toner is selectively transferred to a region of the photoreceptor that has received light of an intensity that is greater than a predetermined value. The predetermined value is equal to or greater than 40% and equal to or smaller than 60% of an average peak intensity of the plurality of the light emitting elements that are driven with a maximum current value.
