IPC: G03G15/16
Filed: 2007-03-09
Abstract: <P>PROBLEM TO BE SOLVED: To obtain an image forming apparatus which reduces deformation of a transfer member due to press contact.  <P>SOLUTION: When a designated time passes after transition to a power saving mode, a retractor is operated and a secondary transfer roll is moved to separate from (be released from press contact with) an intermediate transfer belt.

Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that an area of a region with uneven current distribution on a sensing section is large relative to the area of a region with uniform current distribution, and on-resistance is increased on the sensing section, and thus a current ratio corresponding to a cell ratio is unable to be achieved in a MOSFET that integrates the sensing section for detecting operation of main operation sections on the same chip.  <P>SOLUTION: An isolation region is provided at the outer circumferential portion of a sensing section. The isolation region is provided at a depth to restrain spreading of a region with uneven current distribution that occurs at peripheral edge of the sensing section, thereby allowing restraining the effect of the region with uneven current distribution on the sensing section. Since current distribution can be made more uniform over the entire sensing section, on-resistance of the sensing section can be made close to its design value. As a result, a current ratio in conformity with the design value corresponding to a cell ratio is attained, thereby current detection accuracy is improved.  <P>COPYRIGHT: (C)2009,JPO&INPIT
