What quotes from The Crucible indicate Danforth is ignorant, biased, and cares more about his reputation than his personal integrity?

Danforth most apparently reveals his ignorance at the beginning of act 3, when he is approached by Giles Corey. Giles's wife, Martha, has been arrested on a charge of witchcraft and the old man wishes to testify in the hope that she may be released. When he tells Judge Danforth about the circumstances which he believes may have led to her arrest, the judge's response proves that he is not entirely au fait with the facts. He asks the distraught Giles:

And how do you imagine to help her cause with such contemptuous riot? Now be gone. Your old age alone keeps you out of jail for this.

He haughtily dismisses Giles and accuses him of disrupting the proceedings. Danforth does not present an iota of compassion or understanding for Giles's dilemma. He refuses to believe that the old codger only has his wife's best interests at heart. Instead, he allows his overblown ego to demand that Giles be silent or else charged with contempt. His actions further prove his ignorance about the Salem community, how deeply its residents care about family, and how much its citizens are willing to do to protect those they love. Judge Danforth is more interested in procedure than the real facts.

When Reverend Hale tells him that Giles is there to present hard facts, he declares dismissively:

Then let him submit his evidence in proper affidavit. You are certainly aware of our procedure here, Mr. Hale.

The judge's bias is abundantly clear when he says that he believes the girls are God's agents, used to deliver Salem from the Devil's pernicious evil. He first tells Reverend Hale that, "I have until this moment not the slightest reason to suspect that the children may be deceiving me." He then makes it clear that the testimony of those accused of witchcraft should be dismissed while that of the children should be believed for, as he mentions, they are victims and, "we must rely upon her victims—and they do testify, the children certainly do testify."

He makes his prejudice even more apparent when he intimidates Mary Warren by speaking of lying when she wants to tell the truth. He asks her, "Do you not know that God damns all liars? (She cannot speak). Or is it now that you lie?"

Judge Danforth is obviously proud of his reputation. He has earned a name for himself for being harsh. In act 3, he takes much pride in informing Francis Nurse of this fact.

And do you know that near to four hundred are in the jails from Marblehead to Lynn, and upon my signature?

And seventy-two condemned to hang by that signature?

Throughout the trial, the judge assumes a dictatorial stance. He rejects whatever evidence may favor the accused and, alternatively, goes about condemning them and those who testify on their behalf. He is adamant about maintaining his reputation as one who does not bend to reason and does not have much integrity. He relies on the rumors and untruths of those such as Reverend Parris and the Putnams, even though the accused have presented evidence showing these individuals' corruption. An excellent example of his lack of integrity is shown when he tries to persuade John Proctor to withdraw his appeal by stating that Elizabeth is pregnant and won't face execution during her confinement.

. . . if she begin to show her natural signs, you shall have her living yet another year until she is delivered—what say you to that? (John Proctor is struck silent ). Come now. You say your only purpose is to save your wife. Good, then, she is saved at least this year, and a year is long. What say you, sir? It is done now.

Judge Danforth's lack of integrity speaks of one who is determined to prove a point. He is not one to be messed with. He and he alone will determine the guilt of those accused and, as far as he is concerned, they are guilty purely because of the charges against them.
