Comey admits that he did not vote for Obama, and financially supported his opponents, but writes glowingly of the Obama he came to know, describing him as "an extraordinary listener" and a man of kindness and intellect.
Mr Comey, who stands at a tall 6ft8, describes his first impressions of President Trump.
James Comey is embarking on a publicity tour.
"Does anyone really believe that story?" he said at a press conference a year ago after a reporter asked if he had ever "engaged in conduct that you now regret" during past visits to Russian Federation and whether he was vulnerable to blackmail by Russian Federation.

I ensure justice to our daughters - Narendra Modi
He said it was Modi's love and affection for the state that he was leaving no stone unturned for the development of the state. Prime Minister said Government will build 1.5 lakh Health & Welfare Centres across districts.
James Comey's new book has angered Democrats and Donald Trump, there are concerns over some unofficial Humboldt Broncos merchandise, and a look at the volunteers helping to prevent scams on Google Maps. During the segment, Comey said he didn't know whether to believe Trump's denial that he had spent time with prostitutes in Moscow before he became president.
The interviews are Comey's first public comments since he testified before the Senate Intelligence Committee last June, when he accused Trump of firing him to undermine the FBI's Russian Federation investigation.
"He brought up what he called the "golden showers thing" ... adding that it bothered him if there was "even a one percent chance" his wife, Melania, thought it was true", Comey writes in A Higher Loyalty: Truth, Lies, and Leadership, according to the New York Post. "But I don't know".
In attempt to blunt the impact of the new book, the Republican National Committee is waging a widespread campaign to undercut Comey's credibility, including a new website that dubs the former Federal Bureau of Investigation chief as "Lyin' Comey".
Draft Syria resolutions rejected at UNSC
That panel had found that the Syrian air force had dropped sarin on the village of Khan Sheikhun in April of previous year . The watchdog said it has requested the Syrian government to make the necessary arrangements for such a deployment.
Comey had been investigating allegations that Russia meddled in the 2016 presidential election and possible collusion between Russians and the Trump campaign.
The book also includes strikingly personal jabs at Trump that appear created to irritate the president.
"I think it above all is a truthful portrayal of Jim's observations, his feelings and what occurred", Clapper said. Republicans will say on this basis that if Democrats now seize on Comey's criticism of Trump, it's inconsistent.
What struck him most, Comey told ABC, was that the conversation moved straight into a public relations mode, what they could say and how they would position Trump. While Comey does not outline the details of the information - and says he didn't see indications of Lynch inappropriately influencing the investigation - he says it anxious him that the material could be used to attack the integrity of the probe and the FBI's independence.
